Statistical Charts: Bar, Dot, Line, Pie, Scatter
Gbogbo ọrọ náà
Different data calls for different pictures. A bar chart compares categories, a pie chart shows shares of a whole, a line graph follows change over time, and a scatter plot reveals a relationship between two variables. Choosing and reading the right one is a core data skill.
In this lesson you will read, interpret and choose between bar charts, dot plots, line graphs, pie charts and scatter plots, knowing what each display is good at showing.

Stem-and-Leaf Graphs (Stemplots), Line Graphs, and Bar Graphs
One simple graph, the stem-and-leaf graph or stemplot , comes from the field of exploratory data analysis. It is a good choice when the data sets are small. To create the plot, divide each observation of data into a stem and a leaf. The leaf consists of a final significant digit . For example, 23 ha
