An easy trick to solve it is to notice that this distribution has a long right hand tail, meaning that there are individuals with high values of hours spent on TV (higher mean) but they are few (the median is low). Thus, the mean is higher than the median and answer is A

If I had gotten this one wrong, I probably would have given up my plans to become a statistician!!!!!!!

The median is basically the number in a set that is right in the middle of the set. In order to find the median, you first need to WRITE THE NUMBERS IN A SET IN ASCENDING ORDER.

3 - 5 - 6 - 7 - 13 - 17 - 35

Now we need to look at the set and decide which number is in the middle. 7 is the best choice because there are exacltly 3 numbers to its right (13, 17 and 35) and 3 numbers to its left (3.5 and 6).

Qunatity B is thus 7.

The mean is the avarage of all numbers in a set. All we need to do is add all numbers together and divide the result by how many numbeers there are in the set.

3 + 5 + 6 + 7 + 13 + 17 + 35 = 86

There are 7 numbers in this set.

86/7 = 12.3

Quantity A is 12.3

Qunaity A is greater than quantity B. A is the answer.

This histogram can be a bit tricky to read so I may have gotten some of the numbers wrong.

Why are you using the set of students 3 - 5 - 6 - 7 - 13 - 17 - 35 not the set of hours ?

Yes you are right. To answer that question must be used the values on the x axis and NOT those on the y axis

Thank you

I am not able to understand how the set 3 - 5 - 6 - 7 - 13 - 17 - 35 has been derived. Please help me here. I am Lost in the tricky histogram details.

Can someone please help with the question above?

On trick is that the median always follow the tail and the tail goes down

The Mean must be higher than the median

A is the answer
