Melinda takes readings of the depth of water in a
pond every day for 1 week. Here are her results in
meters:
6.5, 6.8, 7.2, 6.8, 6.6, 6.3, 6.4
What are the mean, median, and mode water levels
for the week, rounded to the nearest tenth?
Answer with supporting work:

Answer :

Answer:

a) The Mean of the water levels for the week (μ) = 6.657

b) The Median of the water levels for the week = 6.6

c) Mode = 6.8

Step-by-step explanation:

Step(i):-

Given that the data per one week

6.5,  6.8 , 7.2  ,6.8  ,6.6  ,6.3 , 6.4

we have to find the mean of the given data

Solution:-

Mean = ∑x /n

[tex]Mean = \frac{6.5+6.8+7.2+6.8+6.6+6.3+6.4}{7}[/tex]

Mean = [tex]\frac{46.6}{7}[/tex]

Mean(μ) = 6.657

The Mean of the water levels for the week (μ) = 6.657

Step(ii):-

Given that the data per one week

6.5,  6.8 , 7.2  ,6.8  ,6.6  ,6.3 , 6.4

we have to find the Median of the given data

A median is the center value of a  given  data when arranged in an order

6.3  6.4  6.5 6.6  6.8  6.8 7.2

The Median = middle of the given data

The Median = 6.6

Step(iii):-

Given that the data per one week

6.5,  6.8 , 7.2  ,6.8  ,6.6  ,6.3 , 6.4

we have to find the Mode of the given data

Mode = Value repeated the most number of times

The value 6.8 repeated two times

∴ Mode = 6.8
