Z-score can be used to scale or standardize variables, allowing for comparisons between variables with different units. For instance, you can determine what is more extreme: a 300-gram orange or a 2.05-meter man? Such a comparison is only possible when the variables have been standardized thro...
The area to the left of z = -2.23 is 0.01287. The probability of values falling below this value in a normally distributedpopulationis 0.01287 or 1.287%. Here’s how it looks graphically. This z-table chart is a probability distribution plot displaying the standard normal distribution. The sh...
a z-score in a standard normal distribution. q2 what are the types of z score table? there are two z-score tables which are: positive z score table: it means that the observed value is above the mean of total values. negative z score table: it means that the observed value is below...
