Description
This resources contains the following items:
1) Comparing Overlapping Data NOTES & PRACTICE:
· Informally compare similar data sets visually, giving generalizations about each set
· Informally compare similar data sets by calculating measures of center & variability to support the comparison statements
· Compare the means of similar data sets in relation to their common variability (MAD)
2) Comparing Overlapping Data TEST PRACTICE:
10 Multiple choice questions in two formats:
o Printable
o Version for Google Forms (link included on the first page of the PDF downloaded)
3) Answer Keys
CALCULATOR USE RECOMMENDED (especially if students are allowed to use calculators on state tests).
NOTE: This resource assumes students are proficient in reading dot plots, box plots, and histograms, as well as calculating measures of center (mean, median, mode) and measures of variability (range, IQR, MAD). If your students need review on these topics, check out the following resources from The Math Café, created specifically to support the 7th grade data standards above.
Reviewing Data Displays & Data Measures NOTES, PRACTICE, QUIZ
Data Review: Measures of Center & Variability SCAVENGER HUNTS
Measures of Center & Variability PARTNER PRACTICE Activity
This resource was developed to meet the requirements of the 7th grade math Statistics & Probability standardsà
Draw informal comparative inferences about two populations.
CCSS.MATH.CONTENT.7.SP.B.3 Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability. For example, the mean height of players on the basketball team is 10 cm greater than the mean height of players on the soccer team, about twice the variability (mean absolute deviation) on either team; on a dot plot, the separation between the two distributions of heights is noticeable.
CCSS.MATH.CONTENT.7.SP.B.4 Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations. For example, decide whether the words in a chapter of a seventh-grade science book are generally longer than the words in a chapter of a fourth-grade science book.
