Dot Plots

How to make a dot plot
This video describes and explains the method for making dot plots, and the ways in which they can be useful.
1. Dot plots provide a visual way of displaying all data points on the number line. It is similar to a line plot.
2. Each dot represent one data point, so you can count out the middle data point to find the median.
3. The mode for the data set is the highest column.
Describing a Dotplot
Dot Plot and Skew.



Dot Plot vs. Line Plot
There are two types of Dot Plots. One type of Dot Plot is similar to Line Plot. Another type of Dot Plot has two axis.

Histograms



 
Introduction to Histograms
This video provides an introduction to histograms and explains how to create a histogram from given data.
Represent Data on a Histogram
This video shows how to represent numerical data on a histogram, according to Common Core Standards for Mathematics 6.SP.4. This way of representing the data gives us a way of organizing the data by intervals.


Box Plots

Represent Data on a Box Plot (Box-and-Whisker Plot) / 5 Number Summary
This video shows how to represent numerical data on a box plot, according to 6.SP.4. This way of organizing data gives us a 5 number summary of the data set that includes the minimum, first quartile, median, third quartile, maximum.
Box Plots
Learn that Box and Whisker Plots are graphs that show the distribution of data along a number line. See how to construct box plots by ordering a data set to find the median of the set of data, median of the upper and lower quartiles, and upper and lower extremes. Draw a Box and Whisker plot and learn how to use box plots to solve a real world problem. See how to construct box plots if there are no middle values.


 
Box & Whisker Plots
This video looks at how to create box and whisker plots and find the interquartile range. It includes two examples.
