Dot Plot Statistics Example 1

Follow the full solution, then compare it with the other examples linked below.

Example 1

easy
The number of books students read last month: 0, 1, 2, 1, 3, 2, 1, 0, 2, 1, 4, 2. Create a dot plot and identify the mode.

Solution

  1. 1
    Step 1: List distinct values in order: 0, 1, 2, 3, 4.
  2. 2
    Step 2: Count frequencies: 0→2, 1→4, 2→4, 3→1, 4→1. Place dots above each value on a number line accordingly.
  3. 3
    Step 3: The mode is the value(s) with the highest frequency. Both 1 and 2 appear 4 times, so the data is bimodal with modes of 1 and 2.

Answer

Dot plot has 2 dots above 0, 4 above 1, 4 above 2, 1 above 3, 1 above 4. The data is bimodal with modes 1 and 2.
A dot plot displays each data point as a dot above a number line. Clusters of dots show where data concentrates, making it easy to identify the mode (most frequent value) and see the overall shape of the distribution.

About Dot Plot

A dot plot is a statistical chart that displays the frequency of data values using dots stacked above a number line. Each dot represents one observation, making it easy to see clusters, gaps, and the overall shape of a distribution for small to medium datasets.
