What is the difference between standard deviation and standard error and what is the formula relating the two measures?
Homework Answers
Standard deviation is defined as a spread measure of a set of values that is the spread from the mean of the required valued. The standard error on the other hand is defined as the spread of the sample mean values of the given set of data. By Central limit theorem the distribution of the sample means is given as: (for large enough sample size n)
Therefore the formula relating the 2 measures here is given as:

What is the main difference between the variance and the standard deviation as measures of variability? standard deviation is variability around the median, whereas variance is variability around the mean standard deviation is squared variability around the mean, whereas variance is in the original units variance is for the population, whereas standard deviation is around the sample mean. variance is squared variability around the mean, whereas standard deviation is in the original units

4. Calculating the standard deviation and the estimated standard error for the sample mean difference Aa Aa A researcher is interested in hamster wheel-running activity during the summer versus the winter.
