# What is Statistics in Frequency Distribution?

Statistics deals with a set of data. Sometimes we may be interested in finding the most favorite or frequently used item from a set of data.

## Answer: The concept that deals with data analysis, interpretation, and presentation of data in a more meaningful way is statistics in the frequency distribution.

There are 5 major terms used and calculated as statistics in the frequency distribution.

**Explanation:**

1. Mean (Average of the data) =∑xi / N

xi - refers to all the terms in the data set

N - refers to the total number of terms

2. Median - The value separating the higher half from the lower half.

If 'n' is odd, Median = (n+1)^{th} / 2 value

If 'n' is even , Median = (1 / 2) {(n/2)^{th }term + (n_{2}+1)^{th }term}

n - number of values in the data set.

3. Mode = The most frequently occurring value in a data set.

4. Variance = σ^{2 }=∑(xi − x)^{2}N

5. Standard Deviation = √Variance or √∑(xi − x)^{2}N
