10
100
Find the median: 45, 79, 100, 62, 20, 28, 100.
62.

The circle gaph shows us what information?
Percentages of a whole.
100
What is the range of the following data set: 62, 79, 100, 67, 25, 60.
75.
100
Generally speaking, does an outlier affect the mean of a set of data?
Yes.
200
TRUE or FALSE: To compare and contrast two variables over time we use a histogram?
False! A histogram shows the FREQUENCY of items in intervals and is a 'snapshot' in time.
200
Find the median of the following data set: 8, 7, 7, 7, 7, 10
The median is 7.
200
What measure of central tendency represents the "middle" of the data set?
Median
200
How do you calculate "Range?"
Subtract the lowest number in the data set from the highest number in the data set.
200
Which type of graph shows the distribution of data along with the median and outliers?
The Box and Whiskers Plot shows the distribution, median and any outliers.
300
What is the more commonly used term for "Mean?"
Average
300
True or False: A histogram has no spaces between the bars (columns) on the x-axis.
True. A histogram's bars are at INTERVALS with no spaces in between them.
300
What is the median of the following data set: 26, 100, 46, 99, 25, 75, 50.
50.
300
What graph shows a change of something over time?
The line graph shows a change over time.
300
What two measures of central tendency are LEAST likely to be affected by an outlier?
Median and Mode
400
Assuming that Brittany played 33 basketball games this season, how many total points did she score if her average points per game was 15?
495 points
400
Assuming a large data set, is median impacted by an outlier?
No.
400
Is having a MODE of zero and having no MODE the same thing?
No! Example: 0,0,0,3,7,5 AND 3,2,6,7,1,10
400
TRUE or FALSE: Bar Graphs and Histograms are exactly the same way to show meaning for data.
False! Bar Graphs can have spaces between the items listed on the x-axis. Histograms have INTERVALS that never have spaces between them.
400
True or False: It is possible to find an outlier in every data set.
False! There are many data sets that do not have an outlier.
