Find the mean, median, and mode of 3, 5, 1, 5, 1, 1, 2, 3, 15 after each data value increases by 4. The mean is and the
The median is
The mode is

Median:

Mode:

If we increase each element in the data set by , our new data set will be...

The mean of a data set is the sum of all of its elements divided by the number of elements.

Solving for the mean:

The median of a data set is just the middle number if and only if the elements of the data set is arranged according to how less to how great each element is.

If we arrange our data set it will be...

We can do see that our middle number is so this our median.

The mode of a data set is the number that repeated the most. We can see in our data set that the number repeated times. and is . and is . Since is the number that repeated the most, this is our median.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
