Question

A bakery wanted to make their muffins more uniform in size. They reworked their equipment to do so. To test the changes, they made 25 muffins then measured each one. Which of the following should they use to determine whether or not the equipment changes worked?

Select one:

a.
mean

b.
mode

c.
range

d.
interquartile range

Answer 1

The bakery should use the mean to determine whether or not the equipment changes worked. The mean is the average of all the measurements and can help determine if the muffins are more uniform in size. If the mean is similar to the previous batch of muffins, then the equipment changes did not work. If the mean is more consistent and closer to the desired size, then the equipment changes were successful.
