2 Statistics: tally charts and frequency tables

Worked example 1

If you throw a dice 12 times, how many times

do you think each number will appear?

I think the Your idea about

dice will land on each what you think will
number twice. happen is called

Throw the dice 12 times. a conjecture.

Use tally marks to record the results of each throw.

For example:

11 22 33 44 55 66

The dice has not landed on each number twice, so your

conjecture is wrong.

These are chance throws, so there will be more than one answer
each time you do this activity.

Now try it yourself and compare your results with a partner’s results.
