Answer 2

Answer:

The value of the first quartile of the abovementioned data set is 40. The answer to the abovementioned question is option A which states, "40".

Explanation:

There are data of 9 students and we need to arrange them in ascending order to find our answer.

So, the arrangement looks like the following:

⇒ 25, 35, 45, 50, 60, 80, 90, 95, 100

We know,

The Median of numbers is always the middle number.

So, we can safely conclude that 60 is the Median of the abovementioned arrangement.

Thus,

The 1st Quartile =  Median of test scores = 60

∴ The numbers to the left of the Median are as follows:-

• 25,
• 35,
• 45,
• 50

The Median of the numbers on the left of the median is 60 = $\frac{35+45}{2}$ = $\frac{80}{2}$ = 40

Thus, the answer is 40.

Answer) We can safely conclude that the answer to the abovementioned question is 40.
