Your variable of interest should be continuous and normally distributed, and you must know the average and spread (or standard deviation) of the population. Thus, if the sample size were 20, there would be 20 observations; It can be used to make a judgement about whether the sample differs significantly on some axis from the population from which it was originally drawn. Web whether you’re ruling social media, acing tests, or just love playing with numbers, the one sample z test calculator is your secret to uncovering the epic story behind your data. Enter the sample mean into the designated field.
S = 100.0 z = x ¯ − μ s / n = 207.0 − 210.0 10.0 / 60 = − 2.32379. University of new south wales. Web single sample z score calculator. [10] [30] [50] [100] [250]

The tool also compares the sample data to the standard deviation, calculates the test power, checks data for normality and draws a histogram and a distribution chart. The population standard deviation must also be known. Web in many situations, the degrees of freedom are equal to the number of observations minus one. S = 100.0 z = x ¯ − μ s / n = 207.0 − 210.0 10.0 / 60 = − 2.32379.
