How do you find the population variance?The population variance is the variance of the population. To calculate the population variance, use the formula σ2=1NN∑i=1(xi−μ)2 σ 2 = 1 N ∑ i = 1 N ( x i − μ ) 2 where N is the size of the population consisting of x1,x2,…
What are the values for SS and variance for the following sample of N 4 scores 1 3 0 4?What are the values for SS and variance for the following sample of n = 4 scores? Scores: 1, 3, 0, 4a. ss=10 and variance=2.5b.
What is the value of SS for the following set of scores 0 1 4 5?Answer and Explanation: Scores are: 0,1,4 and 5. Hence the value of SS is 17 and none of the options is correct.
