Descriptive statistics: describes and summarizes data. You are just describing what the data shows: a trend, a specific feature, or a certain statistic (like a mean or median). Inferential statistics : uses statistics to make predictions.

A pie chart gives a simpler visual representation of category frequencies by cutting a circular plot into wedges or slices whose sizes are proportional to the relative frequency (percentage) of occurrence of specific data categories. Some pie charts can have a one or more slices emphasised by ‘exploding’ them out from the rest of the pie.

What is a Pie Chart? A Pie Chart is a type of graph that displays data in a circular graph. The pieces of the graph are proportional to the fraction of the whole in each category. In other words, each slice of the pie is relative to the size of that category in the group as a whole.

Mar 25, 2024 · Descriptive statistics refers to a set of statistical methods used to summarize and present data in a clear and understandable form. It involves organizing raw data into tables, charts, or numerical summaries, making it easier to identify patterns, trends, and anomalies.

Two graphs that are used to display categorical data are pie charts and bar graphs. In a pie chart, categories of data are represented by wedges in a circle and are proportional in size to the percent of individuals in each category.

Pie graphs are used to show the distribution of qualitative (categorical) data. It shows the frequency or relative frequency of values in the data. Frequency is the amount of times that value appeared in the data. Relative frequency is the percentage of the total. Each category is represented with a slice in the 'pie' (circle).

Pie Chart. A pie chart is a useful graphical representation for qualitative data. For example, the US Census Bureau compiled the following chart for single mothers.

Create a pie chart for a categorical variable for which values add up to 100%. Go to the “Analyze” menu and select “Descriptive Statistics,” then “Frequencies.” Select the variable of interest for the pie chart from the list on the left, then click on the arrow in the middle. Click “Charts” on the right. Then choose “Pie Chart.”

Pie chart There are two main types of graph for looking at categorical data. The first is named a pie chart; this is due to the fact that a circle is divided into slices that represent each of the categories. Figure 4 shows a pie chart of M&M colors taken in a random sample. Unfortunately, it is difficult for a reader to precisely

In this chapter, you will study numerical and graphical ways to describe and display your data. This area of statistics is called “Descriptive Statistics.” You will learn how to calculate, and even more importantly, how to interpret these measurements and graphs.
