Essential concepts and terminology to understand this topic
A set of five descriptive statistics — minimum, Q1, median, Q3, and maximum — used to summarize a dataset.
The smallest data point in a dataset.
The median of the lower half of a dataset, representing the 25th percentile.
The middle value of a dataset when ordered, dividing it into two equal halves.
The median of the upper half of a dataset, representing the 75th percentile.
The largest data point in a dataset.
The difference between the maximum and minimum values in a dataset.
The range between Q3 and Q1, representing the middle 50% of the data.
A data point significantly different from other values in a dataset, often identified using IQR.
A graphical representation of the five-number summary, showing the distribution of a dataset.
Lines extending from the box in a box plot to the minimum and maximum values, excluding outliers.
The way data values are spread or arranged in a dataset.
A dataset is symmetric if its distribution is mirrored around the median.
A measure of the asymmetry in the distribution of data values.
