Skewed to the left box plot
Webb22 mars 2024 · If the curve is shifted to the left or to the right, it is said to be skewed. What does a left skewed box plot mean? Skewed data show a lopsided boxplot, where the median cuts the box into two unequal pieces. If the longer part of the box is to the right (or above) the median, the data is said to be skewed right. WebbSkewed Left (negatively skewed) - fewer data plots are found to the left of the graph (toward the smaller numeric values). The "tail" of the graph is pulled toward the lower or negative numbers, or to the left. The mean typically gets pulled toward the tail, and is less than the median. (There may be exceptions to the this last statement.)

We will compute it by taking the median of the lower half of the data set. For example, the exam scores data set has n = 35 n = 35 data values. The median, M = 77 M = 77, was the 18th data value. So Q1 Q 1 will be the median of the 17 values below 77.

It is good practice to examine both a graphical and a numerical summarization of your data. These summaries are often part of the evidence that researchers use to support any conclusions drawn from the data.
