Percent difference. Percent change is a special case of percent difference. (It’s change if it’s for the same things, usually people, across time.) Both percent difference (see the following section) and the difference between two percentages (see Chapter 5) come up all of the time [but they’re not the same thing, so be careful!].

Difference (() = 92.5 – 89 = 3.5 Equation I. Calculate percent difference by dividing the Difference (() by the Grand Mean. % Difference = 3.5/90.75 x 100 = 3.85% Evaluating Results. Obtain the cumulative CV of your quality control level that is closest to the grand mean from step #5 in the procedure above.

To find the percent of error, you find the difference between the predicted value or amount and the actual value (subtracting the absolute value of the numbers so that you do not get negatives). The numerator is this difference. Next you divide by the denominator which is the estimated or predicted amount. You will get a decimal outcome.

Use Excel to plot T2 vs. hanging mass. T2 should be in seconds2 (y-axis) and hanging mass should be in kg (x-axis). Use Excel to find the best fit line. The slope of the best fit line will allow you to determine the spring constant, k. Remember that . If we square both sides of this equation we get:
