Answer:
Mean = 6.8
Median = 7
Mode = 7
Step-by-step explanation:
Observations: 4, 6, 5, 7, 9, 8, 10, 4, 7, 6, 5, 9, 8, 7, 7
No. of observations = 15
Mean = Sum of observations / No. of observations = (4+6+5+7+9+8+10+4+7+6+5+9+8+7+7)/15 = 102/15 = 6.8
Now, Mode is the most repeated term. Here, 7 is the mode as it occurs the maximum no. of times.
To find the median, first arrange the data in ascending or descending order. Here, I'll arrange in ascending order.
4, 4, 5, 5, 6, 6, 7, 7, 7, 7, 8, 8, 9, 9, 10
No. of terms (n) = 15. This means that n is odd. When n is odd, median = (n+1)/2th term = (15+1)/2th term = 16/2th term = 8th term = 7.
Hence, 7 is the median.
