How to calculate the mean and median of a data set?

Calculate the mean, median, mode and range for 3, 19, 9, 7, 27, 4, 8, 15, 3, 11. How to Find the Mean (or Average Value) To figure the mean, add up the numbers, 3+3+4+7+8+9+11+15+19+27=106 then divide it by the number of data points 106/10=10.6. How to Find the Median

What is the median of the numbers in ascending order?

In ascending order the numbers are 3, 3, 4, 7, 8, 9, 11, 15, 19, 27. There are 10 total numbers, so the 5th and 6th numbers are used to figure the median. (8+9)/2 = 8.5 If there were 9 numbers in the series rather than 10 you would take the 5th number and would not need to average the 2 middle numbers.

What does it mean when the mean is higher than median?

When the mean is greater than the median, and the median is greater than the mode (Mean > Median > Mode), it is a positively skewed distribution. It’s described as ‘skewed to the right’ because the long tail end of the curve is towards the right. In the sample graph below, the median and mode are located to the left of the mean.

How do you find the mean and median of a frequency curve?

If a frequency distribution graph has a symmetrical frequency curve, then mean, median and mode will be equal. Mean = Median = Mode. For Positively Skewed Frequency Distribution. In case of a positively skewed frequency distribution, the mean is always greater than median and the median is always greater than the mode. Mean > Median > Mode.
