Z-Score Formula
Z= X- μ/σ
Where,
- Z is the Z-score.
- X is the value to standardize.
- μ is the mean of the distribution.
- σ is the standard deviation, which measures the spread of the data.
Z-Score Table
Z Score Table is the table for determining the probability of a standard normal variable falling below or above a certain value. Z-score table, also known as a standard normal table or z-score Table, is a mathematical table that provides the area under the curve to the left of a z-score in a standard normal distribution. The standard normal distribution is a bell-shaped curve with a mean of 0 and a standard deviation of 1.
The z-score table is used to find the probability that a random variable from a standard normal distribution will fall below a certain value. In this article, we will learn about the Z Score Table in sufficient detail and also learn how to use the Z Score Table in numerical problems.
