Intro to Biostatistics
The 50th percentile, also known as the median, is the value that separates the higher half from the lower half of a data set. This means that 50% of the observations fall below this value and 50% are above it, making it a crucial measure of central tendency that helps summarize and interpret data distributions. Understanding the median is essential because it provides insight into the overall distribution of data, especially in skewed distributions where the mean might not be representative.
