The mean and median of Data set A are close to each other.
The mean of the data sets are within 3 units from each other.
The correct option is (B) and (F)
What is mean, median, standard deviation and Variance?
- The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list.
- The median is the middle value in a list ordered from smallest to largest.
- Standard deviation is the spread of a group of numbers from the mean.
- The variance measures the average degree to which each point differs from the mean.
Data Set A: 25 26 27 28 29 30 31 32 33 34 35
Data Set B: 25 26 27 28 29 30 31 32 33 34 35
For Data A,
- Mean = 29.77
- Median = 29.5
- Standard Deviation =3.5651
- SSD= 3.6577
- Variance= 12.71
- Standard variance =13.3789
For Data B,
- Mean = 29.29
- Median = 29
- Standard Deviation = 2. 4794
- SSD= 2.5438
- Variance= 6.1475
- Standard variance =6.4711
So, from above observation we can see that:
The mean and median of Data set A are close to each other.
