Out of the total people 15 people rated it with 1 star, 20 people rated it with 2 stars, 30 people rated it with 3 stars, 10 people rated it with 4 stars and 5 people rated it with 5 stars. What will be the final prediction if we take the average of individual predictions? Correct Answer 3

Given that we are taking the average of individual predictions to make the final prediction. Average = ∑ (Rating * Number of people) / Total number of people = ((1 * 15) + (2 * 20) + (3 * 30) + (4 * 10) + (5 * 5)) / 80 = (15 + 40 + 90 + 40 + 25) / 80 = 210 / 80 = 2.625 And the nearest integer is 3. So the final prediction will be 3.
