Recording collected data

Worked solution

1. 1

   Count the dog answers.

   $\text{Dog:}3$

   Dog appears first, third and sixth in the list, so its frequency is three.

2. 2

   Count each remaining category.

   $\begin{array}{c}\text{Cat:}2\\ \text{Fish:}1\end{array}$

   Cat appears twice and fish appears once; each listed answer belongs to just one category.

3. 3

   Check the response total.

   $3+2+1=6$

   The frequencies account for the six answers in the list.

Worked solution

1. 1

   Add the two known counts.

   $4+3=7$

   Seven of the ten children chose Tag or skipping.

2. 2

   Find how many votes remain.

   $10-7=3$

   The remaining children all chose handball, so handball has three votes.

3. 3

   Check all three groups together.

   $4+3+3=10$

   The completed counts match the ten children who voted.
