What is a Z-Score and Probability in Statistics?
\n
A Z-score, also known as a standard score, measures how many standard deviations a specific data point is away from the mean of its distribution. It is a crucial concept in statistics that allows us to standardize values from different normal distributions, making them comparable.
\n
The probability associated with a Z-score represents the area under the standard normal distribution curve to the left of that Z-score. It tells us the likelihood of observing a value less than or equal to the specific value in question.
