WebJan 21, 2024 · The z-score is a measure of how many standard deviations an x value is from the mean. To convert from a normally distributed x value to a z-score, you use the following formula. Definition 6.3. 1: z-score (6.3.1) z = x − μ σ where μ = mean of the population of the x value and σ = standard deviation for the population of the x valueWebCovariance between two discrete random variables, where E(X) is the mean of X, and E(Y) is the mean of Y. Note that we only know sample means for both variables, that's why we have n-1 in the denominator. If the covariance is positive, then increasing one variable results in the increase of another variable.

So in this situation the mean is going to be one over this probability of success in each trial is one over six. So it's equal to six. So one way to think about it is on average, you would have six trials until you get a one. WebIn statistics, the mode is the value in a data set that has the highest number of recurrences.
