### Overview

Introduction to Statistical Analysis Using IBM SPSS Statistics (V23) provides an application-oriented introduction to the statistical component of IBM® SPSS® Statistics. You will review several statistical techniques and discuss situations in which they would use each technique, the assumptions made by each method, how to set up the analysis, as well as how to interpret the results. This includes a broad range of techniques for exploring and summarizing data, as well as investigating and testing underlying relationships. You will gain an understanding of when and why to use these various techniques as well as how to apply them with confidence, interpret their output, and graphically display the results.

**Test the Difference between the Means of Two Groups**

- Use the Chart Builder to create an error bar and boxplot to visualize the difference between groups
- Use Explore and Means to describe the differences between groups
- Use the Independent-Samples T Test to test whether the difference between two group means is statistically significant

**Test the Differences between More than Two Group Means**

- Use One-Way ANOVA to determine whether there are statistically significant differences between means of three or more groups
- Use post hoc tests to identify differences between group means

**Test the Relationship between Scale Variables**

- Use the Chart Builder to create a scatterplot to assess the relationship between two scale variables
- Explain when the correlation can be used
- Perform a hypothesis test on the correlation

**Predict a Scale Variable**

- Use Regression to predict a scale variable with one or more scale variables
- Use Automatic Linear Modeling to predict a scale variable with categorical and scale variables

**Use Nonparametric Tests**

- Describe when Nonparametric Tests should and can be used
- Use Nonparametric Tests for two or more independent samples
- Use Nonparametric Tests for two dependent samples
