Question

Find d, if Σf = 80 and Σf, d, = 176.​

Answer 1

Answer:

The value of d is 2.2

Step-by-step explanation:

Frequency distribution is a statistical representation of the distribution of values or observations in a dataset. It displays the number of times each value or observation occurs in the dataset.

Data are frequently organized and summarised using the frequency distribution, which also aids in finding patterns or trends in the data. The values or observations are listed on one axis of a table or chart, while the associated frequencies are listed on the other axis.

The given information is

Σ$f_{i}$ = 80 and

Σ $f_{i}d_{i}$ = 176.​

We need to evaluate the value of d.

We have,

d = Σ $f_{i}d_{i}$ / Σ$f_{i}$

$d = \frac{176}{80} = 2.2$

Therefore, the value of d is 2.2
