By adding all numbers in set together and then total is divided by number of scores in that set, we obtained
geometric mean
standard deviation
Arithmetic Mean
variance
Table which shows frequency of each score is called a

frequency distribution table
pi chart
polygon
When cumulative frequencies are plotted against end points of their respective class intervals and joined together, resultant graph is called
