Question 2
Jyoti scored the following marks (out of 10) in different subjects 5, 7, 0, 3, 5, 8.
Jyoti calculated mean, median and mode from the remaining numbers ignoring 0. Did she do it correctly?

Answer 1

Jyoti did it correctly.

Step-by-step explanation:

Jyoti scored the following marks(out of 10) in different subjects 5, 7, 0, 3, 5, 8.

Mean is the average of the given marks.

Mean = $\frac{5 + 7 + 0 + 3 + 5 + 8}{6} = \frac{28}{6} = 4.66666$

If we ignore 0 then there is no change in the value of Mean.

Median is the middle of the given marks when arranged in ascending order.

0, 3, 5, 5, 7, 8

Median = $\frac{5+5}{2} = \frac{10}{2} = 5$

If we ignore 0 then there is no change in the value of Median.

Mode is the number that occurs the most often.

Here, 5 occurs two times.

So, Mode = 5

If we ignore 0 then there is no change in the value of Mode.

Hence, Jyoti did it correctly.
