Problem of the Day

Find the five-number summary and draw a box and whisker plot for the following set of data:

16, 25, 14, 6, 16, 9, 26, 31, 20, 18, 26, 13

Aim: How can we construct a histogram and a cumulative frequency histogram?

The following set of data represents the scores on a mathematics quiz:58, 79, 81, 99, 68, 92, 76, 84, 53, 57,81, 91, 77, 50, 65, 57, 51, 72, 84, 89

Complete the frequency table below and, on the accompanying grid, draw and label a frequency histogram of these scores.

Guided Practice

Aim: How can we construct a histogram and a cumulative frequency histogram?

The scores on a mathematics test were 70, 55, 61, 80, 85, 72, 65, 40, 74, 68, and 84. Complete the accompanying table, and use the table to construct a frequency histogram for these scores.

The accompanying table shows the weights, in pounds, for the students in an algebra class.Using the data, complete the cumulative frequency table and construct a cumulative frequency histogram on the grid below

Guided Practice

Aim: How can we construct a histogram and a cumulative frequency histogram?

Twenty students were surveyed about the number of days they played outside in one week. The results of this survey are shown below.

{6, 5, 4, 5, 0, 7, 1, 5, 4, 4, 3, 2, 2, 3, 2, 4, 3, 4, 0, 7}

Complete the frequency and cumulative frequency tables below for these data Graph the cumulative data.
