Mode in Statistics
The mode is a measure of central tendency that represents the value or values that appear most frequently in a dataset. Unlike the mean and median, which summarize the dataset as a whole, the mode focuses on the most common value(s).
Finding the Mode
1. List the data: Identify the frequency of each value in the dataset.
2. Determine the highest frequency: The value(s) that occur(s) most often is/are the mode(s).
Types of Mode
- Unimodal: A dataset with a single mode.
- Bimodal: A dataset with two modes.
- Multimodal: A dataset with more than two modes.
- No mode: A dataset where no value repeats.
Example
Let’s consider the following dataset representing the number of books read by a group of students in a month:
\[ 4, 2, 4, 5, 3, 4, 2, 2, 3, 2 \]
To find the mode:
1. List the data and count the frequency of each value:
\[
\begin{align*}
\text{Value:} & \quad 2, 3, 4, 5 \\
\text{Frequency:} & \quad 4, 2, 3, 1 \\
\end{align*}
\]
2. Determine the highest frequency:
The highest frequency is 4 (for the value 2).
3. Identify the mode:
The value with the highest frequency is 2.
So, the mode of the number of books read by the students is 2, as it appears most frequently in the dataset.
This example demonstrates how to identify the mode by counting the frequency of each value and selecting the one that occurs most often.
