Answer:
Mean = 4.7
Mode = 5
Median = 5
Step-by-step explanation:
Mean = Σfx / Σf
Σfx = (3*4) + (4*5) + (5*7) + (6*2) + (7*2) = 93
Σf = (4+5+7+2+2) = 20
Mean = 93 / 20
= 4.65
= 4.7
Mode = highest occurring = vlaue with highest frequency = 5
Median :
20 / 2 = 10
Value corresponding to the 10th term = 5
