Find and interpret the mean absolute deviation of the data.
1 answer:
Using it's concept, it is found that:
- The <em>mean absolute deviation</em> is of 26.
- It means that the values differ from the mean by an average of 26.
The mean of a data-set is given by the <u>sum of all observations divided by the number of observations</u>.
The mean absolute deviation of a data-set is the <u>sum of the absolute value of the difference between each observation and the mean, divided by the number of observations</u>.
The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the data-set is: {101, 115, 124, 125, 173, 165, 170}.
Hence, the mean is:
Then, the mean absolute deviation is:
Hence:
- The <em>mean absolute deviation</em> is of 26.
- It means that the values differ from the mean by an average of 26.

Look at the graph below carefully
Observe the results of shifting ={2}^{x}f(x)=2x
vertically:
The domain, (−∞,∞) remains unchanged.
When the function is shifted up 3 units to ={2}^{x}+3g(x)=2x +3:
The y-intercept shifts up 3 units to (0,4).
The asymptote shifts up 3 units to y=3y=3.
The range becomes (3,∞).
When the function is shifted down 3 units to ={2}^{x}-3h(x)=2 x −3:
The y-intercept shifts down 3 units to (0,−2).
The asymptote also shifts down 3 units to y=-3y=−3.
The range becomes (−3,∞).
