What is the average for tge following set of measurements 7.1g,9.8g,2.3g,8.5g,7.4g,5.7g,

To calculate an average first of all it is necessary to verify that all the measures are in the same units in this case we can see that all the measures are in grams.

1. Subsequently, all values should be added as shown below:

7.1 g + 9.8 g + 2.3 g + 8.5 g + 7.4 g+ 5.7 g=  40.8

2. Divide the result of the sum of all measurements with the total number of measurements performed by the experimenter in this case:

40.8 / 6 = 6.8

To get an average, you must add all of the numbers together, and divide that sum by the amount of numbers there are. There are 6 number, which is what we must divide by.

6.8g is the average for the set of measurements.
