A science class recorded the number of minutes each student spent on a project.

28 Students 1360 minutes
What is the interquartile range

1 answer

To calculate the interquartile range (IQR), you first need the data set in question. Since you have only provided the total amount of time (1360 minutes) and the number of students (28), we cannot determine the IQR without knowing how the 1360 minutes is distributed among the 28 students.

However, if you had the individual minutes spent by each student, you would go through the following steps to find the interquartile range:

  1. Sort the Data: Arrange the minutes each student spent on the project in ascending order.

  2. Find Quartiles:

    • Q1 (First Quartile): This is the median of the first half of the data (the lower 25%).
    • Q3 (Third Quartile): This is the median of the second half of the data (the upper 25%).

  3. Calculate IQR: Subtract Q1 from Q3 (IQR = Q3 - Q1).

If you can provide the individual minutes spent by each of the 28 students, I would be able to help you find the interquartile range.
