Categories » computers and electronics » articlewikihow to analyse data using (the statistical package for the social sciences) software has been developed by ibm and it is widely used to analyse data and make predictions based on specific collections of data. Spss is easy to learn and enables teachers as well as students to easily derive results with the help of a few commands. If you are worried about conducting your data analysis on spss, here are a few guidelines and an overview of the your excel file with all the data. Once you have collected all the data, keep the excel file ready with all data inserted using the right tabular the data into spss. Depending on what you want to analyse, you can give desired commands in the spss software. Giving commands in spss is simple and easy to comprehend, making it an easy task for students to do this by ve the results. You can also consult a professional company which is expert in ate conclusions based on your analysis. The ultimate objective of the spss is to help arrive at conclusions based on specific research. The software helps you to derive conclusions and predict the future easily with minimum statistical to analyze data in spss from surveys of strongly agree, agree, undecided, disagree and strongly disagree?

Univariate data analysis is a useful way to check is a statistical packages for data analysis, it is popular software because of its friendly social & medical starting this session, you should know how to run a program in windows operating system. Click and hold at lower left of your screen, and among the program listed select spss 16. Click and release the mouse lauanch the clicking of spss this window will open then click on cancel button if you like to enter data in a new file on ok for opening an existing file. A window will open known as data editor with variable are a number of different types of windows in spss. Some of the frequently used windows are:Data editor window: it displays the contents of the data file. In this window, you can create new data files or modify existing you open more than one data file, each data file has a separate data editor window. The data editor es two view of the data:Data view: it displays the data values. This window opens automatically the first time a procedure that generates tasks in spss are performed by selecting appropriate "pull-down" menus. Here are some data editor window menus and their uses:File menu: from the file menu you can open several different existing files or a database file such excel file or read in a text file. You can also save any changes to the current menu: from the edit menu, you can cut, copy, paste, insert variables, insert cases, or use find data editor menu: the data menu allows you to define variable properties, sort cases, merge files, split files,Select cases and use a variable to weight orm menu: the transform menu is where you will find the options to do some computations les, to create new variables from existing ones or recode old e menu: the analyze menu is where all statistical analysis takes place. From descriptive statistics sion analysis to nonparametric menu: the graph menu is where you can create high resolution plots and graphs to be edited chart editor window or you can create interactive ies menu: the utilities menu is used to display information on the contents of spss data files or -ons menu: from the add-ons menu you can run other packages like conjoint, classification trees, networks. Also there are programmability extensions that allow you to integrate programs like python into spss.
In this case it is the data editor : the help menu allows you to get help on topics in spss or to ask the statistics coach some window in spss has its own toolbars that provides access to common tasks. You can show, move or hide a status bar is at the bottom of each spss window and provides the following information:Command status: gives information about a procedure that is status: filter on shows when a subset of cases in the data is used for status: weight on indicates that a weight variable is being used in the file status: split file on indicates that the file has been split into separate groups for menu selections will open dialog boxes. The box in any statistical procedure has the following parts:Source variable list: a list of variable types (allowed by the procedure) from the working data variable lists: one or more lists of variables needed for the d push buttons: buttons that can be used to run the procedure by opening a subdialog box to onal specifications. The command syntax is pasted into a syntax window,Where it can be modified for future analysis. This creates the code regularly known as spss : deselects any selections, and resets all specifications in the dialog box and any subdialog boxes to the default : cancels any change in the dialog box settings since the last time it was opened. This will close the dialog : provides help about the current dialog name of each spss variable in a given file must be unique; it must start with. If more decimals entered (or computed by spss), the additional information will be retained internally but yed on screen. To change or edit a variable label, simply click gh the variable label goes a long way to explaining what the variable represents, for (discrete data of both nominal and ordinal levels of measurement), we often need to know s represent which categories. For whole numbers, drop the decimals down to you select a string variable, you can tell spss how much "room" in memory for each value, indicating the number of be allowed for data entry in this string you are satisfied with the definitions of each value, click on the ok real beauty of value labels can be seen in the data view by clicking on the "" icon in the tool bar , which switches between the numeric values. View of different variables with their you click missing button the spss will display sometimes want to signal to spss that data should be treated as missing, even though there is numerical code recorded instead of the data actually being missing (in which case spss displays period -- this is also called system missing data). Button missing cell, i declared "9", "99", and "999" all to be treated by spss as missing (i. These values will columns property tells spss how wide the column should be for each variable.
The column size indicates space is allocated rather than the degree to which it is alignment property indicates whether the information in the data view should be left-justified, right-. Since spss does not differentiate al and ratio levels of measurement, both of these quantitative variable types are lumped "scale". Nominal and ordinal levels of measurement, however, are we have data set with different we need to enter in spss, below is set les and data set, this file is named sor christopher conducted a study on subjects; the variable description is as with subject sex (0 = female, 1= male). Ph- parents eh ng data into data this lesson our goal is only, how to enter, save, and edit data (the data sheet given above). The first step ng the data into data editor is to define all the variables. Creating a variable requires us to name it,Specify the type of data (nominal, ordinal, scale) and assign label to the variables and data values if needed. Move the cursor to the bottom of the data editor, named as variable view and click it, a different grid appears. When the cursor moves to the type column , a small grey button marked with three appear, click on it you see this dialog box, numeric is default variable type, click that the measure column (far right column) be put on scale, because you took numeric as , in spss, each variable carry a descriptive label to help identify its meaning. Because sex is categorical (qualitative ) variable and we are going to represent it numerically ( analysis purpose, because spss only entertains quantitative variable). In similar way we will add all the variables, the variable view window will be seen switch to data view by clicking the appropriate tab in the lower left of screen. When you are done all,The data editor should look clicking the third button (named value label) at left most you will see the screen as is wise to save all your work in a disk file. To save a file, click on file menu, choose save as …, then next to file name, bp, then click g the data file/ edit any value, just to open the data file and click edit menu, the case or variable which is required for you have completed your work, it is important to exit the program propoerly.
Since we saved every thing earlier, click we discuss the issues like, transform,Select, split, compute new variables,Re-coding of data, merging files, sorting,Transpose, weighted tool allows you to rearrange the file data sort variable then some values are missing in data/variables be replaced by different methods, le is categorical then the value is the researcher on his/her ence, but the variable is continuous, help using the replace missing d.

N gives a brief description of the aim of the statistical test, when it is used, e showing the spss commands and spss (often abbreviated) output with a brief interpretation of . For more information on the hsb data of the examples in this page will use a data file called hsb2, high beyond. This data file contains 200 observations from a sample of high ts with demographic information about the students, such as their gender (female),Socio-economic status (ses) and ethnic background (race). For example, using the hsb2 data file, say we wish to r the average writing score (write) differs significantly from 50. For example, using the hsb2 data file, say we wish to r the proportion of females (female) differs significantly from 50%, i. For example,Using the hsb2 data file, say we wish to test whether the mean for the same for males and females. Notice that the spss syntax for the wilcoxon-mann-whitney test is almost that of the independent samples t-test. We will use the same data file (the hsb2 data file) and the same variables in this example as we did in the independent t-test example above and will not assume that write,Our dependent variable, is normally distributed. In spss, the chisq option is used on tics subcommand of the d to obtain the test statistic and its associated p-value.
Using the hsb2 data file, let’s see if there is a relationship between the type attended (schtyp) and students’ gender (female). However, if this assumption is in your data, please see the section on fisher’s exact test below. In spss unless you have the spss exact test module, only perform a fisher’s exact test on a 2×2 table, and these results ted by default. One-way analysis of variance (anova) is used when you have a categorical le (with two or more categories) and a normally distributed interval le and you wish to test for differences in the means of the dependent down by the levels of the independent variable. For example, using the hsb2 data file, say we wish to test whether the mean of s between the three program types (prog). To see the mean of write for each level tables = write by this we can see that the students in the academic program have the highest g score, while students in the vocational program have the textbook examples: design and analysis, chapter es: applied regression analysis, chapter faq: how can i do anova contrasts in spss? We will use the same data file as the one way e above (the hsb2 data file) and the same variables as in e above, but we will not assume that write is a normally distributed interval. For example, using the hsb2 data file we will test whether the mean of read is equal to. Continuing with the hsb2 dataset several above examples, let us create two binary outcomes in our dataset:Hiread. Tables=himath by r’s chi-square statistic suggests that there is not a icant difference in the proportion of students in the proportion of students in -way repeated measures would perform a one-way repeated measures analysis of variance if you had rical independent variable and a normally distributed interval dependent was repeated at least twice for each subject. We have an example data set called rb4wide,Which is used in kirk’s book experimental design. In this data set, y is ent variable, a is the repeated measure and s is the variable tes the subject will notice that this output gives four different p-values.
No matter which p-value , our results indicate that we have a statistically significant effect of a textbook examples from design and analysis: chapter library: advanced issues in using and understanding spss code fragment: repeated measures ed measures logistic you have a binary ed repeatedly for each subject and you wish to run a sion that accounts for the effect of multiple measures from ts, you can perform a repeated measures logistic regression. This can be done using command and indicating the probability distribution and logit as the link function to be used se data file contains. For example, using the hsb2 data file we will look g scores (write) as the dependent variable and gender (female) -economic status (ses) as independent variables, and we will include ction of female by ses. Note that do not need to have the interaction term(s) in your data set. Rather, you spss create it/them temporarily by placing an asterisk between the variables make up the interaction term(s). However,That interaction between female and ses is not statistically significant ( textbook examples from design and analysis: chapter faq: how can i do tests of simple main effects in spss? Library: an overview of spss perform a friedman test when you have one within-subjects le with two or more levels and a dependent variable that is not normally distributed (but at least ordinal). Spss handles this for you, but in tical packages you will have to reshape the data before you can conduct. For example, using the hsb2 data file we will create an ordered variable called write3. If this was not the case, we different models (such as a generalized ordered logit model) be the relationship between each pair of outcome data analysis examples:Ordered logistic ted output: ordinal logistic ial logistic regression. For example, using the hsb2 data file we will use female as our dependent variable,Because it is the only dichotomous variable in our data set; certainly not because practice to use gender as an outcome variable. For example, using the file we can run a correlation between two continuous variables, read and write.

However, the is that two canonical variables are identified by the analysis, of which seems to be more related to program type than the minant function library: a history of spss statistical (multivariate analysis of variance) is like anova, except that there are two dependent variables.
