Mean(x) = 4 + 8 + 11 + 19 / 4 = 42/4 = 10.5 Standard deviation = √(4 - 10.5)2+ (8 - 10.5)2+ (11 - 10.5)2+ (19 - 10.5)2/ (4 - 1) = 6.35 Therefore, mean = 10.5, and standard deviation = 6.35 Similarly, you can try the calculator to find the mean and standard...

A common way to quantify the spread of a set of data is to use thesample standard deviation. Your calculator may have a built-in standard deviation button, which typically has ansxon it. Sometimes it’s nice to know what your calculator is doing behind the scenes, or how to find the ...
The final step in calculatingstandard deviationis taking the square root of the variance. This is best done with a calculator since you'll want your answer to be precise and decimals may be involved. For the set of test scores, the standard deviation is the square root of 75.76, or 8.7....
The population standard deviation is the square root of the variance. Use a calculator to obtain this number.(8.9)1/2= 2.983 The population standard deviation is 2.983 Learn More From here, you might wish to review the different standard deviation equationsand learn more abouthow to calcula...
Press the "Stat" button on your TI-83 calculator. Step 2 Move the cursor to "Edit" using the arrows, then select "1:Edit." You should see a spreadsheet with two columns, L1 and L2. Step 3 Clear any preexisting data by moving the cursor to the top of the column, selecting "Clear...
