Bar Graphs and Pie Charts

Bar Graphs and Pie Charts

In this video we'll look at how to build bar graphs and pie charts to represent a data set, and we'll talk about when these types of charts are useful, and when they probably shouldn't be used.
Building Histograms from Data Sets

Building Histograms from Data Sets

In this video we'll work on actually building a histogram from a data set. In order to build a histogram, we'll need to determine the class interval, which means we'll need to look at class width and class midpoint.
Frequency Tables and Dot Plots

Frequency Tables and Dot Plots

In this video we'll look at how to build a dot plot from a frequency table. As the name implies, a frequency table displays the frequency at which different things occur. We can translate the table into a visual representation, called a dot plot,...Show More
Histograms and Stem-And-Leaf Plots

Histograms and Stem-And-Leaf Plots

A histogram, also called a frequency histogram, is just like a bar graph, except that we collect the data into buckets or bins, and then sketch a bar for each bucket. Each bucket needs to be the same size, or width, so that they’re capable of...Show More
Joint Distributions

Joint Distributions

A joint distribution is a table of percentages similar to a relative frequency table. But in a joint distribution, we show the joint distribution of one set of data against the distribution of another set of data. For instance, we could display...Show More
Line Graphs and Ogives

Line Graphs and Ogives

In this video we'll look at how to build line graphs and ogives to represent a data set, and we'll talk about when these types of charts are useful, and when they probably shouldn't be used.
One-Way Tables

One-Way Tables

One-way data tables are data tables with just column headers and one row header, just row headers and one column header, or only column headers or only row headers. We can locate the cell in the table we're referring to just by asking one...Show More
Relative Frequency Tables

Relative Frequency Tables

In this video we'll talk about relative frequency tables, of which there are three types: row relative frequency tables, where we see totals for each row, column relative frequency tables, where we see totals for each column, and total relative...Show More
Two-Way Tables

Two-Way Tables

Two-way data tables are data tables with column headers and row headers. We can locate the cell in the table we're referring to by asking exactly two questions. For instance, if we have a table with years for column headers and months for row...Show More
Venn Diagrams

Venn Diagrams

Venn diagrams can be a great way to illustrate the values in a data set. They let us quickly see where in our data we have similarities and differences. We plot data with similarities in the overlapping part of the diagram, and data with...Show More
