WebFeb 18, 2024 · Understanding Quantiles: Definitions and Uses. Summary statistics such as the median, first quartile and third quartile are measurements of position. This is because these numbers indicate where a specified proportion of the distribution of data lies. For instance, the median is the middle position of the data under investigation. WebWhen we describe shapes of distributions, we commonly use words like symmetric, left-skewed, right-skewed, bimodal, and uniform. Not every distribution fits one of these descriptions, but they are still a useful way to summarize the overall shape of many distributions.

WebDec 20, 2024 · A distribution may be skewed due to a disproportionate number of extremely high or low values, especially if the sample size is small. A distribution may show more or less variation, around the mean. This is quantified by the size of the standard deviation of the distribution.
