Question 1
Which of the below data sets has the lowest standard deviation? You do not need to calculate the exact standard deviations to answer this question.
Do I Make up my own data?
Just plug in your numbers and run 'em through the formula, if you can't tell just by looking.
To determine the data set with the lowest standard deviation, we need to compare the variability in each data set. The standard deviation measures how spread out the data points are from the mean.
To find the data set with the lowest standard deviation without calculating exact values, we can use a simple method called the "range test." The range of a data set is the difference between the highest and lowest values. Generally, data sets with smaller ranges tend to have lower standard deviations.
To apply the range test, compare the ranges of each data set and identify the one with the smallest range. The data set with the smallest range is likely to have the lowest standard deviation.
