Normal/Gaussian
Probability Distribution Calculator
Using the Calculator:
1. Enter
a number in the “Area to the left of” box and click
“Calculate” to get the probability that a standard Normal random variable is less than the number.
2. Enter
a proportion in the box after the “=” and click
“Calculate” to get the Z score that a standard Normal random
variable has the probability of being less than.
3. You
can change the region to be calculated to “Area to the right of” to
get P(Z > “Z Score”) = “Probability”
