Total number of observations , which are below a certain value are known as
variances
class marks
class boundaries
cumulative frequency

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
