The arranged data can be divided into four equal parts by three values. These values are called quartiles and are denoted by Q1, Q2 and Q3. Here Q1 is first quartile, Q2 is second quartile and Q3 is third quartile.
Problem: The time (in minutes) recorded by a sample of 14 students in a quiz competition is 38, 45, 33, 17, 28, 19, 18, 17, 11, 10, 18, 12, 25, and 40. Find Q1, Q2 and Q3.
Problem: The table below reports the monthly internet charges for a sample of 64 students in the month of January. Find the first, second and third quartiles.
I wanted know is there any other formula’s for the Quartiles Calculation, if so can please share it.
Very helpful indeed. Thank you.
