In the previous session, you explored measurement and variation. You learned that there is almost always variation in statistical data, and you looked at potential sources of the variation, including random error and bias. You may also recall that there are four components to statistical problem solving:

Part A:	Patterns in Variation
Part B:	Line Plots
Part C:	Frequency Tables
Part D:	The Median
Part E:	Bar Graphs and Relative Frequencies
Homework

In this session, we will focus on the last two steps of this process -- analyzing data and interpreting results. A proper analysis of data can help you provide better answers to statistical questions. Note 1

In this session, you will learn how to do the following:

Organize data in a line plot and a frequency table

Organize data in a cumulative frequency table

Use intervals to answer a statistical question

Determine the median of a set of data

Determine relative frequencies and create bar graphs of your data

Throughout the session you will be prompted to view short video segments. In addition to these excerpts, you may choose to watch the full-length video of this session.
