First, you need to put them in order
53kg, 55kg, 61kg, 61kg, 76kg, 91kg, 98kg, 105kg, 120kg

For mean, you add them all up and divide by the amount of numbers (9)
720/9 = 80

For median, you find the middle number (76kg)

For mode, you find the number that appears the most (61kg)

Mean: 80
Median: 76
Mode: 61

Mean = 80kg

Add all the numbers together and devide by how many

Median = 76kg

Find the middle number

Mode =61kg

The most frequent number, the number that appears the most.
