mean = 318.3

Median =330

Mode= 200

Step-by-step explanation:

Mean (average) is the total sum of values in a given a data set ÷ number of values

= 3820/12

Mean= 318.3

Median= midpoint value in a given data set. When the data set is an even number, median is calculated with the 2 middle point values as n1 + n2/2

Step 1: we rearranged the data set from least to highest value to give

200,200,220, 240,300,320,340,360,380,400,420 and 440

Median= 320 + 340/2

=660/2 = 340

Mode is the value with highest frequency in a given data set, from the given question, mode = 200
