Data Session 2: Data Organization and Representation

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:

Ask a question
Collect data
Analyze data
Interpret results

In This Session:

Part A:

Patterns in Variation

Part B:

Line Plots

Part C:

Frequency Tables

Part D:

The Median

Part E:

Bar Graphs and Relative Frequencies



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

Learning Objectives

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
