I have 5 boxes with tools. I made an inventory of the number of the tools that exist in the boxes. I have the results of the inventory but I didnt count the correct number of the tools that were existed in the boxes. the actual number of the tools is: box 1 = 5 tools box 2 = 4 tools box 3 = 8 tools box 4 = 9 tools box 5 = 7 tools the inventory is : box 1 = 6 tools box 2 = 7 tools box 3 = 6 tools box 4 = 8 tools box 5 = 8 tools How can I calculate the accuracy % of the inventory referred to the actual number of the tools (per box and summary number) ? Thank you!
