adding a no. to every term increases the median and mean by same no.

It will increase the mean without affecting the median.

The mean will increase from 14 to 20. The median will increase from 12 to 15.

It will not make any difference to either.

Both median and mode are the statistics formulas, Median is called mid value of the given data and mode is the value which occure repetedly in the given data.

median

The median of a data set comprising only one value is that value. So the median of 2.5 is 2.5.

Middle value when the data are arranged in numerical order is the median.

The median is the middle value in a set of data. It is the value that separates the higher half of the data from the lower half. If there is an even number of data points, the median is the average or mean of the two middle values. If there is an odd number, just arrange the data in order from smallest values to largest and the middle one is the median.

Not an extreme value.

it messes up the mean and sometimes the median. * * * * * An outlier cannot mess up the median.

The middle value in a data set is the median. If there are an even number of values in the set, you average the middle two values to get the median.

You will need to put the un-grouped data in ascending or descending order. If you have an odd number of data values the formula for the median value is (n+1)/2. Example my data in ascending order is 0, 2, 4, 5, 7, 8, 9. I have 7 data values. The median is the value (7+1)/2 = 4th value from left or right which is 5. For an even number of data values, you will need to calculate the median and it may not be a data value. It will be the mean of the two center values. Use the formula n/2 to get the left most value. Example my data in ascending order is 0, 2, 4, 5, 7, 8. I have 6 data values. The left most value I will use to calculate the median is 6/2 = 3rd. The 3rd value from the left is 4. The next value is 5. Median is (4+5)/2 = 4.5.

The median value is: (52+58)/2 = 55

When adding and subtracting a constant amount means that that amount will increase. The amount will increase dew to adding each number.

The mean, the median, the mode and the upper and lower limits of the range would each be reduced by the amount subtracted.
