WebAs mean is always pulled toward the extreme observations, the mean is shifted to the tail in a skewed distribution [Figure [Figure1b 1b and andc]. c]. Mode is the most frequently occurring score and hence it lies in the hump of the skewed distribution. Median lies in between the mean and the mode in a skewed distribution.[6,7] WebMar 1, 1990 · Descriptive statistics include measures of central tendency and variability. Measures of central tendency include mean, median, and mode. The mean is the arithmetic average of data from interval or ratio scales. The median reflects the 50th percentile score.
