# Analyzing Data

Explore ways of analyzing data, including displaying sumary tables and plotting and analyzing lines of best fit.

#### Plotting Values in Graphs

Learn how to plot values in graphs to display computed quantities. You will learn how plotted values behave when a graph is split and how to remove plotted values.

#### Working with Summary Tables

Summary tables display the results of calculations on the collection as a whole. In this movie you will learn how to add attributes and formulas to a summary table.

#### Using Regression Lines in Scatter Plots

In this movie you'll see both a least-squares regression line and a median-median line and see how the latter is more resistant to outliers than the former. You'll also see how valuable it can be to split the data into groups and get a regression line for each group.

#### Determining a Best Fit by Minimizing Sum of Squares of Residuals

Learn how to show the squares of the residuals for lines and curves, and how to use these to determine a best fit.

#### Plotting Functions in a Scatter Plot

Learn how to plot a function in a scatter plot and then edit that function to vary it dynamically.

#### Using a Residual Plot

A residual plot helps you look for patterns in the data that are not explained by a fitted curve or line. In this movie you'll learn how to make them and read them.
