Question

explore dot plots and histograms
you learned about statistical questions and data
in this lesson, you will learn about displaying and
data distributions with dot plots and histograms.
use what you know to try to solve the problem below.
the parks department can add one
new program to its summer camp.
the data show the ages of children
who have signed up. based on
data set: ages in years, which age
group should get the new program?
ages in years
10 6 8 8 14
10 9 7 11 10
see page 051 for the complete
data set
math toolkit connecting cubes, counters, graph paper, sticky notes, unit tiles
discuss it
ask: how does your
model show the age
groups?
share: in my model,
i showed the age
groups by...

Explanation:

Step1: Count the frequency of each age group

• For the age group \(3 - 5\): There are \(0\) children in the given data set.
• For the age group \(6 - 8\): The ages \(6\), \(8\), \(8\) are in this group. So the frequency is \(3\).
• For the age group \(9 - 11\): The ages \(9\), \(10\), \(10\), \(10\), \(11\) are in this group. So the frequency is \(5\).
• For the age group \(12 - 14\): The ages \(14\) is in this group. So the frequency is \(1\).
• For the age group \(15 - 17\): There are \(0\) children in the given data set.

Step2: Determine the age group with the highest frequency

Since the age group \(9 - 11\) has the highest frequency (\(5\)) among the non - zero frequency groups.

Answer:

The \(9 - 11\) age group should get the new program.
