Question

Explain the meaning of the following terms: frequency?

Answer 1

Here, we have to use the concept of frequency from the statistics. The concept of frequency is generally used for a data analysis in which the values of data repeat. So, repetition of some value is generally known as the frequency.

Complete step by step solution:
Frequency is defined as the number of times a value or some particular data either a discrete data or class interval data is repeating itself.
For example: let us roll a six face dice for 15 times and we get 2, 5, 6, 1, 1, 4, 2, 3, 5, 4, 2, 5, 6, 2, 1.
Therefore in this case we have

So, the maximum frequency is 4 which is number 2.
Here, frequency of number 2 is 4 which means number 2 came 4 times when we rolled dice 15 times.
Similarly minimum frequency is 1 which is of number 3.

Note:
Statistics is the science of collecting some data in the form of the number and studying it to forecast or predict its future possibility. An array is an arrangement of numbers or symbols in rows and columns. Frequency is defined as the number of times a value or some particular data is repeating itself. Frequency arrays help us a lot for the prediction and probability purpose and it also helps us to analyse the real life data like to predict the sale of some specific product or to analyse the sales of the same type of products in the market. Also Frequency distribution is defined as the distribution of frequency corresponding to some class intervals.
