Q&A for How to Find Mode, Median, Mean and Range

She would have to write (in no particular order): 5, 6, 6, 6, 6, and 7. The mean is (5+6+6+6+6+7) ÷ 6 = 36/6 = 6. The mode is 6, because there are more sixes than any other number. The median is 6, because if the six numbers are written in either descending or ascending order, the average of the two middle numbers (6 and 6) is 6. The range is 2, because the difference between the highest and lowest numbers (7 and 5) is 2.

The same way you usually would. Find the difference between the highest and lowest numbers, and if one of those happens to be zero, then just use zero.

This would be a multi-modal data set where each number is a mode.

That series is bi-modal, meaning it has two modes, 5 and 9.

The answer should be 17. Mode is the difference between the highest value (24) and the lowest value (7) there for the answer should have been 17 { 24-7=17}.

The range would be 8. This is because you subtract the lowest number in the data set from the highest, so it would be 9-1.

For the median, we need to find the value in the center. When the values are not in ascending or descending order, the middle value cannot be accurately determined. For example in 1, 6, 2, 8, 4, if we look at it in that order, the median is 2. But when we arrange it in descending order of 8, 6, 4, 2, 1, we find that the median is 4, which is accurate. Whether it is arranged in ascending or descending order is of no significance since the center value is the same for both the orders, If we arrange the above example in ascending order, 1, 2, 4, 6, 8, the median is still 4.

The median is the average of the two middle numbers. So add the two numbers and divide by 2. See Part 2 Step 3 above.
