MULTIPLE SELECT QUESTION

A group of students measures the distance a toy car has traveled after different amounts of time. A table of the data is shown. The students want to perform an analysis of the data set and consider removing the outlier point.
SELECT ALL OF THE QUANTITIES THAT WILL CHANGE IF THE OUTLIER POINT IS REMOVED FROM THE DATA SET.
HINT: Use DESMOS to determine the MEAN and MEDIAN of the data WITH and WITHOUT the OUTLIER!
TIME: 5,6,7,8,9,10,11,12,13,14,15
DISTANCE: 1,1.2,2.4,3.3,3.7,11,4.2,3.7,4.8,4.5,4.9
Mean of the TIME
Mean of the DISTANCE
Median of the TIME
Median of the DISTANCE
Range of the DISTANCE
Answer explanation
If you use DESMOS to find the MEAN and MEDIAN of the TIME and DISTANCE data, you can REMOVE THE OUTLIER VALUE (time 10 seconds, or distance 11 meters) to see whether the measure changes.
Time Mean: Was 10, STAYS 10 if 10 is removed
Dist. Mean: CHANGES (decr.) if 11 is removed
Time Median: Was 10, STAYS 10 if 10 is removed
Dist. Median: Was 3.7, STAYS 3.7 if 11 is removed
Dist. Range: CHANGES from 1-11 to 1-4.9

MULTIPLE CHOICE QUESTION

Answer explanation
For a table of values to "REPRESENT Y AS A FUNCTION OF X" -- each x-value can be paired up with only ONE y-value.
In a table of values, if an X-VALUE REPEATS, it means the x-value is paired with MORE THAN ONE y-value.
There are NO REPEAT X-VALUES in TABLE B, so table B "represents y as a function of x."
