Answer 2

Hi Tra'von,

For mean, you need to add all the times up then divide by how many there are (10). This is the same as taking the average.

For median, order the numbers least to greatest then find the middle. Since there are an even number of numbers, you will have to take the mean of the 5th and 6th numbers.

For mode, you need to find the number(s) that occur most frequently. Sometimes there is no mode if every number is unique, sometimes there are multiple if multiple numbers are duplicated.

Hope that helps!
