Can you help me understand what an Upper Quartile is?
Yes, I can help you understand what an Upper Quartile is.
An Upper Quartile (Q3) is a measure of central tendency that divides a dataset into four equal parts. It is also known as the third quartile or 75th percentile. The Upper Quartile separates the top 25% of the data from the rest of the distribution.
To calculate the Upper Quartile, you need to find the value that is greater than 75% of the other values in the dataset. This value can be found by ordering the data from smallest to largest and then finding the median of the upper half of the dataset.
The Upper Quartile is useful in understanding the spread of a dataset and identifying outliers. It is often used in box plots to indicate the range of data between the median and the highest value.
