"Web1 mrt. 2024 · Quartile 1 = 2 and Quartile 3 = 7. Median divides the data set into two equal parts – the left part and the right part. The middle point of the left part is quartile 1 and the middle point of the right part is quartile 3. You have learned how to find quartiles for discrete data. For continuous data, the idea behind quartiles remains the same. " - How to calculate median for continuous data

Median for Discrete and Continuous Frequency Type Data …

WebIn this example the middle numbers are 21 and 23. To find the value halfway between them, add them together and divide by 2: 21 + 23 = 44. then 44 ÷ 2 = 22. So the Median in this example is 22. (Note that 22 was not in the list of numbers ... but that is OK because half the numbers in the list are less, and half the numbers are greater.) WebThe Data. This is the data set with which we’re going to be working. So we’ve got three variables here: (a) duration – which is the duration in seconds it takes to complete a certain task; (b) sex – male or female; and (c) height – in inches. You want to find out the median of the duration variable.
