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 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:
1. Ask a Question
2. Collect Data
3. Analyze Data
4. Interpret Results
Learning Objectives
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:
Previously Introduced:
data
quantitative data
variation
New in This Session:
cumulative frequency
cumulative frequency table
discrete data
distribution

frequency bar graph
frequency table
interval
line plot
median
mode
relative frequency
