In descriptive statistics, the interquartile range tells you the spread of the middle half of your distribution. Quartiles segment any distribution that’s ordered from low to high into four equal parts. The interquartile range (IQR) contains the second and third quartiles, or the middle half of your data set., The standard deviation for Physics is s = 12. A z score indicates how far above or below the mean a raw score is, but it expresses this in terms of the standard deviation. The z-scores for our example are above the mean.

With method B and n = 20 we find an average of 114.69. But if we first log-transform the data we find, on average, 1.64, which back-transforms to 10 1.64 or 43.65, which is much closer to the true population value of 44.16., A graph of intelligence quotient (IQ), a measure of human intelligence, is an example of normal distribution, in which the most frequent scores are clustered near the center. The mean score is 100. The shaded region between 85 and 115 accounts for about 68 percent of the total area, hence 68 percent of all IQ scores., Wealth by wealth percentile group. Note: Distributions by generation are defined by birth year as follows: Silent and Earlier=born before 1946, Baby Boomer=born 1946-1964, Gen X=born 1965-1980, and Millennial=born 1981 or later.
