Overview of Data Analysis

In this chapter you learn how to calculate statistics on your data. With data analysis, you can

• produce frequency tables or compute summary statistics, correlations, or confidence intervals about the mean

• calculate linear regression, logistic regression, or regression with correction for autocorrelation

• calculate analysis of variance, nonparametric ANOVA, or t-tests

• produce control charts and perform capability analysis

• compute principal components or canonical correlations and calculate seasonal adjustment of time series

• compute percentiles, standardize or rank data, create time-series data, and convert frequency of time-series data.

This chapter describes only the Summary statistics item of the Elementary task from the Data Analysis menu. The other tasks are similar.

The example in this chapter produces a report, as shown in the following display, that shows some summary statistics for the price and square footage of houses for sale.
