Mean=3.3 Median=4 Range=4.1 Mode=4.3

Work Step by Step

You have the values:3.7, 0.2, 4.3, 4, 4.3 To find the mean you have to add all the values together and divide by 5:$\frac{3.7+0.2+4.3+4+4.3}{5}$=3.3 Arrange the numbers from least to greatest (0.2, 3.7, 4, 4.3, 4.3) to find the median. The middle number is 4. The range is the largest value minus the smallest so 4.3-0.2=4.1 The mode is the number that repeats the most which is 4.3 because it occurs twice. So the mean=3.3, Range=4.1,Median=4,Mode=4.3
