MA19.7A.27
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. [Grade 7, 11]

Unpacked Content

Knowledge

Students know:

Populations can be compared using measures of center and measures of variability

Skills

Students are able to:

informally assess the degree of visual overlap of two numerical data distributions with similar variabilities.
Measure the difference between the centers by expressing it as a multiple of a measure of variability.

Understanding

Students understand that:

outliers skew data, which in turn affects the display.
Measures of center give information about the location of mean, median and mode, whereas measures of variability give information about how spread out the data is.

Vocabulary

Visual overlap
Measure of variability
Data distribution
