Scatterplots & Correlation
A double line graph compares these two things.
What are two data sets over time?
The sum of values divided by the number of values.
What is the mean?
This display uses stems and leaves to show the frequency of data.
What is a stem-and-leaf plot?
A double line graph compares these two things.
What are two data sets over time?
The likelihood of an event happening, written as a fraction, decimal, or percent.
What is probability?
If two box plots overlap a lot, what does that indicate about their data?
What is similarity in data spread or center?
The middle number in an ordered data set.
What is the median?
A graph that shows the minimum, Q1, median, Q3, and maximum.
What is a box plot (box-and-whisker plot)?
If two box plots overlap a lot, what does that indicate about their data?
What is similarity in data spread or center?
Flipping a coin once gives this sample space.
What is {Heads, Tails}?
A data set with an IQR of 15 has this compared to a set with an IQR of 5.
What is more variability (less consistent)?
The number that appears most often in a data set.
What is the mode?
An extreme value much larger or smaller than most of the data.
What is an outlier?
A data set with an IQR of 15 has this compared to a set with an IQR of 5.
What is more variability (less consistent)?
Events where one does not affect the other, like rolling two dice.
What are independent events?
The mean of one set is 75, and the mean of another set is 60. Which has the higher average performance?
What is the first set (75)?
The difference between the largest and smallest values.
What is the range?
Which measure of center is least affected by outliers?
What is the median?
The mean of one set is 75, and another set’s mean is 60. Which has the higher average performance?
What is the first set (75)?
A bag has 4 red, 3 blue, and 3 green marbles. Probability of drawing red?
What is 4/10 = 2/5 = 40%?
The difference between “correlation” and “causation.”
What is: correlation shows a relationship, but causation proves one variable causes the other?
A measure of spread that shows the distance between the first and third quartiles.
What is the interquartile range (IQR)?
The average distance each data point is from the mean.
What is the Mean Absolute Deviation (MAD)?
The difference between “correlation” and “causation.”
What is: correlation shows a relationship, but causation proves one variable causes the other?
The probability of rolling a sum of 7 with two dice.
What is 6/36 = 1/6 ≈ 16.7%?
