Step by step explained

Answer:

Median of the data is 157.

Step-by-step explanation:

We are given with Data set of Discrete series.

We have to find the Median Value of given data set.

Step 1: Since the Data set is already in increasing order. We find the cumulative frequency.

Table with cumulative frequency is attached.

Step 2: Now, We find the value of (\frac{N+1}{2})^{th} term.

here, N = 387

So, value of (\frac{387+1}{2})^{th}=(\frac{388}{2})^{th}=194^{th} term

Step 3: Now Median = Value of x for which cf is greater than or equal to (\frac{N+1}{2})^{th} term.

Here,

Median = 194^{th} term = 157

Therefore, Median of the data is 157.
