How to show % increase when accuracy decreases?
Ok, I'm stuck on this one and hope you can help
Here is the sample data Date 1 2 3 Made 1167 1318 1225 Passed 1121 1203 1209 Passed - As a % of Made 96% 91% 99% % Increase in Accuracy 0% X% Y% 1. The €˜Date will continue for an indeterminate amount of time. 2. The €˜Made are the total produced for each €˜Date and may increase or decrease from the prior €˜Date. 3. The €˜Passed are derived from how many of the €˜Made did not fail. 4. The €˜Passed €“ As a % of Made is equal to €˜Passed divided by €˜Made as shown as a % and could never exceed 100%. a. Example: For Date 1 1121 / 1167 * .01 = 96% 5. The €˜% Increase in Accuracy is the problem, I need to derive for €˜Date 2 the percentage of increase of €˜Passed parts as it is related to €˜Date 1 and show it as an increase or decrease trend towards 100% accuracy. 6. Then I need to derive for €˜Date 3 the percentage of increase of €˜Passed parts as it relates to €˜Date 2 and so on€¦ So I need to solve for X% and Y% as a trend towards the goal of 100% passed. Thanks in Advance. |

How to show % increase when accuracy decreases?
Note: In example 4a, you should not be multiplying by .01 as that would give
you less than 1% as an answer. I think you've overthinking the problem. The change is -5% and 8% respectively. Just subtract the two values. Note that even though you passed more parts, the raiot of pass/made decreased, thus your percentage is negative (process is getting worse, not better) -- Best Regards, Luke M *Remember to click "yes" if this post helped you!* "tibado" wrote: Ok, I'm stuck on this one and hope you can help Here is the sample data Date 1 2 3 Made 1167 1318 1225 Passed 1121 1203 1209 Passed - As a % of Made 96% 91% 99% % Increase in Accuracy 0% X% Y% 1.
