Back to Tutor Intake Assessment: Understand that a set of data has a distribution

6.SP.A.2 Tutor Intake -- Reading a Distribution

Concepts

1

A statistics class collects 25 students' heights and writes them
as a plain list of numbers. What do we call the structured
pattern that appears when those same values are plotted as dots
above a number line?

2

A dot plot's number-line axis runs from 50 to 66, so the axis's
middle point is 58. But almost all of the dots are clustered
between 52 and 56. Where is this distribution's CENTER?

B

Procedures

1

A tutor asks a student to describe the SPREAD of a dot plot
showing values from 52 to 65. The student answers "13." At this
stage of the lesson (before any single-number measures have been
introduced), is "13" the expected kind of answer?

2

A sibling-count distribution has most students at 0 or 1
siblings, with a long tail stretching out toward higher values
like 5 and 8. What is this shape called?
