• Maximum (Max): The largest value in the dataset. It represents the highest data point in the dataset.
• First Quartile (Q1): Also known as the lower quartile or 25th percentile, Q1 is the value below which 25% of the data falls. It is the median of the lower half of the dataset.
• Median (Q2): The median, also known as the second quartile or 50th percentile, is the middle value of the dataset when it is sorted in ascending order. It divides the dataset into two equal halves, with 50% of the data falling below it and 50% above it.
• Third Quartile (Q3): Also known as the upper quartile or 75th percentile, Q3 is the value below which 75% of the data falls. It is the median of the upper half of the dataset.
