Introduction To How To Create and Explore a Data Set

Once data have been collected, we must confront the question, “How do we summarize these data clearly and efficiently?” Graphs can help answer this question. We will explore the use and misuse of graphs, along with applications of the most common types of graphs.

Data Sets and Variables

There is much talk around the world about big data and analytics. Imagine the amount of data that big companies have stored up by recording every interaction with a customer. What did the customer search for? What did the customer purchase? How much does a given customer spend in an average order, or over the course of a year? The data must be organized and structured in very particular ways or it would be worthless. The same is true of observations in psychological science, or any science. The observations must be collected and stored in an organized way so that they may be useful for later analysis. This module introduces basic concepts about how data sets are organized and inspected.

Graphing Data

This module explores the general nature of graphical representations of data and their usefulness, and then specifically explores the use of frequency distributions for different types of data.

Creating Graphs With Statistical Software

In this module, we explore the use of bar graphs and histograms to describe a data set. We also introduce the jamovi statistical analysis software program, which we then use to create bar graphs and histograms.
