A frequency distribution of numerical data where the raw data is not grouped.
Add it all together, and then divide it by the number of data entries that there are.
Mean and median are the measures of central location that always have one value. This is true for a set of grouped or ungrouped data.
Suppose you compare the mean of raw data and the mean of the same raw data grouped into a frequency distribution. These two means will be
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.
