Simply put, a z-score (also called a standard score) gives an idea of how far it is from the average value of a data point. More technically it is a measure of how many standard deviations below or above the given population mean a raw score. A z-score can be placed on a normal distribution curve.
Mówiąc wprost, wynik z-score (nazywany również standardowym wynikiem) daje wyobrażenie o tym, jak daleko jest on od średniej wartości punktu danych. Bardziej technicznie jest to miara tego, ile standardowych odchyleń poniżej lub powyżej danej populacji oznacza wynik surowy. A positive z-score means the data point is greater than the mean, and a negative z-score means a data point is lesser than the mean. The z-score formula for a population's data is given as: z = (x - μ)⁄σ. Where z is the z-score, x is the raw score, μ is the population mean, and σ is the population standard deviation.
A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean.
A Z score, also known as a standard score, represents how many standard deviations a data point is from the mean of a set of data. It provides a way to compare the relative position of a value within a data set, allowing for standardized comparisons among different data sets or within the same data set. Formula: What is Z-Score? Z-score also known as the standard score gives us an idea of how far a data point is from the mean. It indicates how many standard deviations an element is from the mean. Hence, Z-Score is measured in terms of standard deviation from the mean. The z-score, also referred to as standard score, z-value, and normal score, among other things, is a dimensionless quantity that is used to indicate the signed, fractional, number of standard deviations by which an event is above the mean value being measured.
Z-scores are also used as part of Z-tests to test whether an observed outcome is statistically significant. Z-test A Z-test is a type of statistical hypothesis test that is used when the test statistic exhibits a normal distribution and the standard deviation of the population is known.
