The standard deviation is used to tell how far on average any data point is from the mean. The smaller the standard deviation, the closer the scores are on average to the mean. When the standard deviation is large, the scores are more widely spread out on average from the mean. The standard deviation is calculated to find the average distance ...

Variance and Standard Deviation for Grouped Data. The procedure for finding the variance and standard deviation for grouped data is similar to that for finding the mean for grouped data, and it uses the midpoints of each class. Example . The data represent the number of miles that 20 runners ran during one week.

The standard deviation and variance is computed from grouped data using the same idea used here: treat every observation in a class as though it fell at the midpoint of that class. R. Comparison of measure of central tendency: mean, median, mode, midrange, midhinge

standard deviation. directly from grouped data. The formula for the mean is: where. Summation in both cases is over i, that is, the rows or frequenices. Combining the two equations above we get: ∑i fi xi ————— ∑i fi The formula for the variance is: Again, summation is over i (rows).
