Question

during the last four days lee studied for 3 hours, 2.5 hours, 1.5 hours, and 3 hours. what is his median study time

Answer 1

$(a + b + c + d) \div x$

a, b, c, and d stand for each of the variables in the equation.

x stands for the number of variables in the equation

Whenever you are finding the Median, first add all variables. You must then divide the sum of those variable by the number of variables involved.

In this case:

$(3 + 2.5 + 1.5 + 3) \div 4$

Answer: Lee studied a median of 2.5 hours over the last 4 days.
