Example of SPSS Analysis

Scenario: A researcher wants to investigate the relationship between age and income. They collect data on age and income from a sample of 100 individuals.

Data Analysis:

• Descriptive Statistics: The researcher calculates the mean, median, and standard deviation of age and income.
• Correlation Analysis: The researcher uses SPSS to calculate the correlation coefficient between age and income to determine the strength and direction of the relationship.
• Regression Analysis: The researcher performs a regression analysis to predict income based on age.

Visualization:

• Scatter Plot: The researcher creates a scatter plot to visualize the relationship between age and income.
• Regression Line: The researcher adds a regression line to the scatter plot to represent the predicted relationship between age and income.

Reporting:

• Table: The researcher creates a table summarizing the correlation coefficient and regression results.
• Report: The researcher writes a report summarizing the findings of the analysis, including the descriptive statistics, correlation analysis, regression analysis, and visualizations.

SPSS Modules

SPSS offers various modules that provide specialized statistical tools for specific research areas. Some common modules include:

• SPSS Statistics Base: The core module of SPSS, providing basic statistical procedures and data management features.
• SPSS Advanced Statistics: Offers advanced statistical procedures, such as multilevel modeling, structural equation modeling, and time series analysis.
• SPSS Regression: Provides tools for regression analysis, including linear regression, logistic regression, and generalized linear models.
• SPSS Amos: A module for structural equation modeling, allowing users to test complex relationships between variables.
• SPSS Exact Tests: Provides exact tests for analyzing small samples or data that do not meet the assumptions of parametric tests.
