SPSS Data Analysis Tutorial Video114

Introduction

SPSS (Statistical Package for the Social Sciences) is a powerful statistical software package that is used by researchers in a wide variety of fields. SPSS can be used to perform a variety of statistical analyses, including descriptive statistics, inferential statistics, and regression analysis. This tutorial will provide you with the basics of using SPSS to analyze data.

Getting Started

The first step is to import your data into SPSS. You can do this by clicking on the "File" menu and selecting "Open." SPSS can read a variety of file formats, including .csv, .xls, and .sav. Once you have imported your data, you will need to create a new data set. To do this, click on the "Data" menu and select "New Data Set."

Exploring Your Data

Once you have created a new data set, you can begin exploring your data. To do this, click on the "Analyze" menu and select "Descriptive Statistics." This will generate a table that provides you with a summary of the data, including the mean, median, mode, and standard deviation for each variable.

You can also use SPSS to create graphs of your data. To do this, click on the "Graphs" menu and select the type of graph you want to create. SPSS can create a variety of graphs, including histograms, scatterplots, and line charts.

Performing Statistical Tests

SPSS can be used to perform a variety of statistical tests. To do this, click on the "Analyze" menu and select the type of test you want to perform. SPSS can perform a variety of tests, including t-tests, ANOVA, and regression analysis.

Once you have selected the type of test you want to perform, you will need to specify the variables that you want to test. You can do this by clicking on the "Variables" button. Once you have specified the variables, you can click on the "OK" button to run the test.

Interpreting Results

Once you have run a statistical test, you will need to interpret the results. The results of a statistical test will typically include a p-value. The p-value is the probability of obtaining the results that you did if the null hypothesis is true. A p-value of less than .05 is considered to be statistically significant, which means that the results are likely due to something other than chance.

In addition to the p-value, the results of a statistical test will also include a confidence interval. The confidence interval is a range of values that is likely to contain the true population mean. The confidence interval will be wider for larger sample sizes and narrower for smaller sample sizes.

Conclusion

This tutorial has provided you with the basics of using SPSS to analyze data. With practice, you will be able to use SPSS to perform a variety of statistical analyses and interpret the results.
