The z score for a value of 1380 is 1.53. That means 1380 is 1.53 standard deviations from the mean of your distribution. Next, we can find the probability of this score using a z table.
WebThe key point to remember is that if you cannot use the pooled estimate of standard deviation, then you cannot use the simple formula for the degrees of freedom. Testing for normality The normality assumption is more important when the two groups have small sample sizes than for larger sample sizes. Web2 de ago. de 2024 · i. = the difference between the x-variable rank and the y-variable rank for each pair of data. ∑ d2. i. = sum of the squared differences between x- and y-variable ranks. n = sample size. If you have a correlation coefficient of 1, all of the rankings for each variable match up for every data pair.
