Interquartile range Wikipedia
mean and median tutorial group size is 5 students, however the groups in semester 2 show more dispersion (or variability in size) than those in semester 1. Dispersion within a dataset can be measured or described in several ways including the range, inter-quartile range and... In descriptive statistics, the interquartile range (IQR), also called the midspread or middle 50%, or technically H-spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles, or between upper and lower quartiles, IQR = Q 3 − Q 1.

MEDIAN and the Quartiles Quartile Statistical Analysis

Sample Quartiles . We have seen that the sample median of a data set {x 1, x 2, x 3,…, x n}, sorted in increasing order, is a value that divides it in such a way, that exactly half (i.e., 50%) of the sample observations fall below...
To find the median and quartiles from grouped data using linear interpolation. Interpolation When you estimate a value between two known values. Example: Suppose a small jar of sweets contains 50 sweets, and a large jar contains 100. We can estimate how many sweets will go in the medium jar. We interpolate (estimate) roughly between these 2 values to get the medium jar containing 75 sweets

  • Quartiles. Quartiles are the values that divide a list of numbers into quarters: Put the list of numbers in order; Then cut the list into four equal parts
  • Data can be presented as simply a list of numbers or descriptions, or it can be organized into groups. In this lesson, you'll learn how to tell the difference between grouped and ungrouped data
  • In descriptive statistics, the interquartile range (IQR), also called the midspread or middle 50%, or technically H-spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles, or between upper and lower quartiles, IQR = Q 3 − Q 1.
