To calculate the mean, you have to first take the sum of all the hours of television watch and then divide that number by the total number of students. In this example, the sum of hours would be: hours = 8+10+5+14+3+6 = 46 hours. Next, you know that the total number of students is 6. Finally, to calculate the mean, take the total number of hours and divide by number of students: 46 / 6 = 7.67 hours.
