Write an algorithm to take the average of only the even values in a dataset. Clearly specify the initialization, repeated steps, and output processing.
List experimental_data is read from input. The elements of experimental_data are separated into thirds. The first third of the data is collected in the beginning of a month, the second third in the middle of a month, and the last third in the end of a month. Integer slice_size represents the number of data in each third. Assign slice_size with len(experimental_data) // 3. Assign early_group with a slice of experimental_data from the beginning up to and excluding index slice_size. Assign mid_group with a slice of experimental_data from index slice_size up to and excluding index (2 * slice_size). Assign late_group with a slice of experimental_data from index (2 * slice_size) up to and including the end.
