To find if the mean is equal to the median, we need to first arrange the data in ascending order: 1, 2, 3, 4, 5, 6, 7. The median is the middle value, which is 4. The mean can be calculated by adding up all values and dividing by the total number of participants: (1+2+3+4+5+6+7)/7 = 4. Therefore, the mean and median are both equal to 4 in this example.
