What is the average for the following set of measurements? 3.1ml,2.7ml,4.6ml,1.9ml,8.7ml a.4.2ml b.21ml c.8.7ml d.3.5ml

The answer would be A. 4.2mL.

You can get the average of the measurements by adding up the measurements and dividing it by the number of measurements.

So in this case, you average will be computed as follows:

=  3.1mL+2.7mL+4.6mL+1.9mL+8.7mL  >        (Add up the measurements)
                              5                                 >       (There are 5 measurements)
 
=  21mL 
       5

=  4.2mL
