I know it has something to do with taking the smallest number of data and the biggest but im not sure exactlyHow do you calculate a percentage of error in data?
Ok so here's how it goes...



%error= absolute value of (result - accepted value) divided by accepted value



then multiply it by 100%



hope that helps!! good luck.How do you calculate a percentage of error in data?
take the absolute value of the experimental value - theoretical value divided by the theoretical and multiplying by 100!How do you calculate a percentage of error in data?
Difference in data/actual data*100



ie: i say there are 50 but there are 48:

50-48=2



2/48*100=100/24=4.17%



I say there are 99 but there are 100:



1/100=1%, I was 1 percent off of the actual data.
