Types of Data Displays
Based on the 2008
AZ State Mathematics Standard
(Grades 1 and 2)
For Grade 1: the pictures/icons in the pictograph represent a quantity of 1.
For Grade 2: The pictures/icons in the pictograph represent more than 1 and a key is required to interpret the graph.
Frequency Table“Favorite Pets”(Grades 2 and 3)
Note: A frequency table may or may not have a column for the tally marks.
Grade 2: Single Bar Graph
Grade 3: Single Bar Graph
Grade 4: Double Bar Graph
Grade 5: Multi-Bar Graph
Vertical Bar Graph
Displays data better than horizontal bar graphs, and is preferred when possible.
Horizontal Bar Graph
Useful when category names are too long to fit at the foot of a column.
Best used for displaying statistical information when there are no more than six components – otherwise, the resulting picture will be too complex to understand.
Pie charts are not useful when the values of each component are similar because it is difficult to see the differences between slice sizes.
Graph paper is a good idea for it is crucial that each recorded X be uniform in size and placed exactly across from each other (one-to-one correspondence).Notice the cluster at 17 & 18 as well as the gap at 13 and 22. The mode is 18, the median is the second X from the bottom for number 18, and the mean is 17.68 or 18.
Line Plot for the Number of M&M's™ in a Package
Perfect linear correlation:A perfect positive correlation is given the value of 1. A perfect negative correlation is given the value of -1.
Strong linear correlation: The closer the number is to 1 or -1, the stronger the correlation, or the stronger the relationship between the variables.
