This is a spreadsheet that you can enter data into in the form in fraction form (i.e. 3 correct out of 5 trials would be 3/5). It converts it to a percentage and then averages all of the trials. If data was not taken on a certain color leave it blank and it will not count toward the average. For letters/numbers I enter a 1 or a 0, either right or wrong and take data more days. For colors and shapes I do multiple trials. Please give me your suggestions to make this better! I always want feedback to make better products and make my teaching better!
