Question

b) The weights (in kg) of students of a class are

38,42,35,37,45,50,32,43,43,40,36,38,43,38

,47

1) Find the mode and median of this​
data

pls give step by step explanation ​

Answer 1

The weights (in kg) of 15 students are,

➻ 38, 42, 35, 37, 45, 50, 32, 43, 43, 40, 36, 38, 43, 38, 47

Now, We've to arrange these weights in ascending order,

➻ 32, 35, 36, 37, 38, 38, 38, 40, 42, 43, 43, 43, 45, 47, 50

We know that,

Mode:

• Mode of a given data is that value of observation which occurs for the most number of times.

Median:

• Median of the given data is the middle observation when the data is arranged in an ascending or descending order.

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━

Here,

38 and 43 is most occuring number in given data, both occur three times.

∴ Hence, 38 and 43 is the mode of given data.

Also,

There are 15 terms in the given data, therefore, the 8th observation of data will be median.

• 8th observation = 40

∴ Hence, Median of given data is 40.
