Mode is also one of the ways to find the central tendency on a group of data.
Imagine us stocking up vegetables at home every day. There are tomatoes, onions, potatoes and brinjals in the mix worth \(Rs.20\), \(Rs.30\), \(Rs.40\), and \(Rs.50\) respectively. Tomatoes and onions as the most used vegetables. We have stocked up potatoes and brinjals for the next three days.
Day | Vegetables bought | Cost (in Rupees) |
Day \(1\) | Tomatoes, Onions, Potatoes, Brinjals | \(20\), \(30\), \(40\), \(50\) |
Day \(2\) | Tomatoes, Onions | \(20\), \(30\) |
Day \(3\) | Tomatoes | \(20\) |
Day \(4\) | Tomatoes, Onions | \(20\), \(30\) |
Which of the vegetables are bought often?
According to the table given, we have bought tomatoes often.
Therefore, we have made purchases worth \(Rs.20\) often.
Thus, \(Rs.20\) is the mode of the group of data.
Mode:
The number that occurs for the maximum number of times in a group of data is the mode.
1. Arrange the numbers in ascending or descending order.
2. Find the number that repeats itself for the maximum number of times.
Important!
Can there be two modes in a set of data?
Yes, if two numbers occur for the equal number of times, then both the numbers are considered as modes of that set of data. This data is known as a bimodal data.
