Webmedian is 1000. It just tries to stay in between. Mean is like finding a point that is closest to all. But it gets skewed. If for a distribution,if mean is bad then so is SD, obvio. Standard deviation is how many points deviate from the mean. For two datasets, the one with a bigger range is more likely to be the more dispersed one.

WebIn descriptive statistics, the interquartile range ( IQR) is a measure of statistical dispersion, which is the spread of the data. [1] The IQR may also be called the midspread, middle 50%, fourth spread, or H‑spread. It is defined as the difference between the 75th and 25th percentiles of the data. WebStandard deviation measures the spread of a data distribution. The more spread out a data distribution is, the greater its standard deviation. For example, the blue distribution on bottom has a greater standard deviation (SD) than the green distribution on top:
WebThe median is a useful measure of central tendency because it is not affected by outliers or extreme values. It is also useful for comparing distributions with different shapes. In this example, the median of 9.93 indicates that the majority of the boat lengths are around 9.93, with fewer boats at the extremes of the distribution. WebThe median is the middle score for a set of data that has been arranged in order of magnitude. The median is less affected by outliers and skewed data. In order to calculate the median, suppose we have the data below: 65 55 89 56 35 14 56 55 87 45 92 We first need to rearrange that data into order of magnitude (smallest first): 14 35 45 55 55 56 56
