However, if you remove five data points from the list it detects only 1 outlier [-99]. That means you need to have a certain number of data size for Z-score to work.

The standard deviation is σ = 4. The individual value we’re interested in is X = 75. Thus, z = (X – μ) / σ = (75 – 80) /4 = –1.25. This tells us that an exam score of 75 lies 1.25 standard deviations below the mean. hwa fong rubber thailand public co. ltd

Web15 Feb 2024 · The value of the z-score tells you how many standard deviations you are away from the mean. If a z-score is equal to 0, it is on the mean. A positive z-score indicates the raw score is higher than the mean average. For example, if a z-score is equal to +1, it is 1 standard deviation above the mean. WebStandard Score. The standard score (more commonly referred to as a z-score) is a very useful statistic because it (a) allows us to calculate the probability of a score occurring within our normal distribution and (b) enables us to compare two scores that are from different normal distributions. The standard score does this by converting (in ...
