Answer:
16 is the median number of dog wals for the first 9 weeks.
Step-by-step explanation:
Before solving this question, know that there is mean, median and mode. What are they?
Mean: It is the average of all the numbers.
Median: It is the middle number when arranged in order.
Mode: It is the most common number that appears.
However, for the question we'll be focusing on median.
To solve:
Knowing that median measn the middle number when arranged in order, we would have to list out all the numbers and find the middle number.
10, 11, 14, 14, 16, 21, 20, 20, 22
Now, we have to list them in order.
10, 11, 14, 14, 16, 20, 20, 21, 22
Now we just have to identify theh middle number. Since there are total of 9 numbers, the fifth digit from the left or right is the median.
∴ 16 is the median number of dog walks for the first 9 weeks.
Hope this helps!
