The second quartile corresponds with the median
The second quartile corresponds with the median.
The median is a measure of central tendency that divides a distribution into two equal halves. It is the middle value when the dataset is arranged in ascending or descending order. In other words, it is the value that separates the lower 50% of the distribution from the upper 50%.
The first quartile marks the 25th percentile, the second quartile (or median) marks the 50th percentile, and the third quartile marks the 75th percentile. Quartiles help to divide a dataset into four equal parts, each containing 25% of the data.
The median is often used to describe the “typical” or “central” value of a dataset, and it can be more robust to outliers compared to the mean. It can be found by taking the middle value when the data is sorted in ascending or descending order, or by interpolating between two values if the dataset has an even number of values.
Therefore, in a distribution, the second quartile corresponds to the median.
