Total number of kernels observed: Click or tap here to enter text.

 

To calculate the number of kernels expected, multiply the total number of kernels observed by the percentage of kernels you predicted would be purple. Then multiply the total number of kernels by the percentage of kernels you predicted would be yellow.  For example, if you predicted 50% of your 150 kernels would be purple, your number of purple kernels expected is 75 and your number of yellow kernels expected is 75.
