In the examples below, we use Stat Trek's Normal Distribution Calculator to calculate probability. In the next lesson, we use normal distribution probability tables. Normal Distribution Calculator The normal distribution calculator solves common statistical problems, based on the normal distribution. The...
Normal distribution calculator finds probability, given z-score; and vice versa. Fast, easy, accurate. Online statistical table. Sample problems and solutions.
the actual distribution of the data may or may not be normal, but as the sample size gets bigger, it can be approximated by a normal distribution. This statistical theory is useful in simplifying analysis while dealing with stock
The example table below highlights some striking deviations from this. They suggest that reaction times 2, 3 and 5 are probably not normally distributed in some population. Last, there's 2 normality tests: statistical tests for evaluating population normality. These are the Kolmogorov-Smirnov ...

Most statistical software will create normal quantile plots. When you look at a normal quantile plot for normality, see if the data: Has extreme values or not. Follows mostly along the line that shows the normal distribution. Falls within the confidence bounds most of the time. ...

As explained above, the standard normal distribution table only provides the probability for values less than a positive z-value (i.e., z-values on the right-hand side of the mean). So how do we calculate the probability below a negative z-value (as illustrated below)?
