51 and 64
What is normally distributed data?
Normally distributed data is the distribution of probability which is symmetric about the mean.
What is mean?
- Mean of some observations is actually the average of those observations.
- Mean can be calculated by adding those observations and then dividing it my the total number of observations.
What is standard deviation?
The statistical measurement which indicates how far a group of numbers is from the mean.
How to find between which numbers scores of 68 percent of the student lies ?
- 68% of a normal distribution lies within one standard deviation of the mean.
Since standard deviation indicates how far the observations deviates from mean,
∴ Scores of 68% of the students will lie between( 57.5 + 6.5 , 57.5 - 6.5)
= ( 51 , 64 ).
