The formula to calculate z-score is. z = (x - μ) / σ . where. z is the z-score, x is the value to be standardized, μ is the mean of the given set of data, σ is the standard deviation of the given set of data. Suppose you are a student and there are total 10 students in your class including you. After the final exam result is published, you want to know how well you performed compared to... So, a high z-score means the data point is many standard deviations away from the mean. This could happen as a matter of course with heavy / long tailed distributions, or could signify outliers. A good first step would be good to plot a histogram or other density estimator and take a look at the distribution.

1.64 is the z-score for the right tail (because the normal distribution is symmetrical). -1.96 is the area in the left tail for a two tailed test 1.96 is the area in the right tail for a two tailed test (because the normal distribution is symmetrical).... The z-score formula starts with this infinite number of distributions and lets us only work with the standard normal distribution. Instead of working with a different normal distribution for each application that we encounter, we only need to work with one special normal distribution.

The z-scores and p-values returned by the pattern analysis tools tell you whether you can reject that null hypothesis or not. Often, you will run one of the pattern analysis tools, hoping that the z-score and p-value will indicate that you can reject the null hypothesis, because it would indicate that rather than a random pattern, your features (or the values associated with your features how to prepare guava fruit to eat Rather than, say, summing normalized scores (z-scores) you really should do the recommended factor analysis. At the same time you can check whether the tests really measure the same thing to
