Sample size (n) = 20
Definition and formula:
Mean: Mean is defined as the average value of the data.
Mode: Mode is the most frequent observation in the data set.
Minimum: The value which is lowest in the data.
Maximum: The value which is highest in the data is called the maximum value.
Sample variance :
Sample standard deviation:
Q1: is the first quartile which shows 25% of the data values under the value of
Q2: is the second quartile or median which shows 50% of the data values under the value of
Q3: is the third quartile which shows 75% of the data values under the value of
Range =Maximum -Minimum
Sample standard error:
Coefficient of variation:
