The area to the left really represents how much (in percentage or decimal value) of the populationįalls within this z score value. Represents the total area under the curve that is right of the z score. Similarly, the area to the right of the z score The area to the left of the z score represents the total area under the curve that is left to the z score. This means that if the whole population fell under the curve, the area would be a value of The total possible value that can be under the curve is 1.00. 8413 of the population or sample set will be the value under the curve. So, again, for example, if the z score is 1. Values are equivalent to the area under the curve. If it is normally distributed, these percentage values will always be the same for their respective z score values. These values will be the same for any sample set or population, as long as it follows the standard 9987 or 99.87% will fall within this range.

9772 or 97.72% of the sample set will fall in this range. 8413 orĨ4.13% of the sample set will fall within this z score value. In standard normal distribution, a certain percentage will lie within given values of z scores (or standard deviations). Standard deviations we are from the mean, we can determine what percentage of a sample set falls into this bracket, as long as the distribution is normally distributed. Statistically speaking, once we know how many

So, again based on the z score, we can determine how many standard deviations we are from the mean. If the z score is 3, then the raw score obtained is 3 standard deviations above the mean. If the z score obtained is 2, then the score obtained If the z score is -1, then the score is 1 standard deviation below the mean. So, for example, if we have a z score of 1, then the score obtained is 1 standard deviation above the mean. The z score, thus, tells us how far above or below average a score is from the mean by telling us how many standard deviations it lies above or The z score is a numerical value which represents how many standard deviations a score is above or below the mean. This Area Under the Curve Calculator calculates the area under the curve based on the z-score entered.
