Number of letter per day 0 1 2 3 4 5
Frequency 28 21 6 3 1 1
Find mode, median, mean, range
Frequency means you have:
 zeros
 1s
 2s
 3s
 4s
5s
so your set is:
 ,,,,,,,,,,, ,,,,,,,,,,,, ,,,,,,,,,,,, ,,,,,,, ,,,,,,,,, => total number 
add all and sum is
recall:
The  is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.
The  is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers.
The  is the number in a data set that occurs most frequently. Count how many times each number occurs in the data set. The mode is the number with the highest tally. It's ok if there is more than one mode. And if all numbers occur the same number of times there is no mode.
mean: is the sum of all the data divided by the count n
median:
Arrange data values from lowest to highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
data values already arranged from lowest to highest value
as you can see,
mode: is the number in a data set that occurs most frequently
in your case  occurs most frequently ( times)
Range:
 (greatest value in set above)
