A normal curve is a theoretical frequency distribution of all possible values in a population,with a 95% probability that any value from that population will fall within 2 standard deviations of the mean.Frequency refers to the number of times a specific value occurs.A statistical inference is made from the study findings obtained from a specific sample and applied to the target population.Levels of significance is a value indicating the chance that values are from different groups when the value of one group is not within the range of values of another group.
