what is the sample variance and standard deviation

gmm = o- 8. Using the same values from Problem 7, calculate the range, sample variance, and sample standard deviation, but this time include 65 in the list of values. How did each of the three values change? - Range: Increases to 65 - 25 = 40. Sample Variance and Standard Deviation: Will increase due to the addition of a much larger value. - Original Range: 16 - New Range (with 65): 40 Original Sample Variance: 19.24 New Sample Variance (with 65): 79.24 Original Sample Standard Deviation: 4.39 New Sample Standard Deviation (with 61'5): 8.90
