Dot plot of 1, 2, 2, 3, 3, 4, 2, 3, 5, 3, 2

Step by step

The question

Question: draw a dot plot of 1, 2, 2, 3, 3, 4, 2, 3, 5, 3 and 2.

Which value is the most common?

1 Draw the number line

The number line goes from the smallest number, 1, to the biggest, 5.

2 Put the dots

The first number is 1.

We cross it out, and put a dot over 1.

Next is 2: a dot over 2.

Another 2: its dot goes on top of the first one.

Every number is crossed out, so every number has its dot.

3 Read the plot

2 has 4 dots.

3 has 4 dots.

Careful!

The mode is the number under the tallest stack, 2 and 3.

Not how many dots it has.

2 and 3 have the tallest stacks.

So both are the most common.

4 Check

Let's check in the list: 2 and 3 come 4 times.

No number comes more often.

So it is right!

Let's look back.

First: draw the number line.

Then: put the dots.

Then: read the plot.

Last: check.
