Slope and Y-intercept
In the linear equation y = mx + b, this letter represents the slope of the line.
What is m?
If a scatter plot shows that as a student's study hours increase, their test scores also increase, the data has this type of correlation.
What is a positive correlation?
The domain of a relation refers to the set of all possible values for this variable.
What is the x-variable (or independent variable/input)?
This measure of center is calculated by adding all the values in a data set together and dividing by the total number of values.
What is the mean (or average)?
What is Mrs. G and Mr. Jamari's favorite color?
This is the slope of a horizontal line.
What is 0 (zero)?
This is the term for a data point on a scatter plot that is far away from the general cluster of the other data points.
What is an outlier?
What is the range of the following set of ordered pairs: {(1, 2), (3, 4), (5, 6)}?
What is {2, 4, 6}?
This value is the middle number in a data set when the numbers are listed in order from least to greatest.
What is the median?
What College does Mrs. G and Mr. Jamari attend?
What is University of Cincinnati (UC) and Central State University?
Find the slope of the line that passes through the points (2, 5) and (4, 11).
What is 3?
This straight line is drawn through the center of the data points on a scatter plot to best represent the trend.
What is the line of best fit (or trendline)?
For a continuous graph that starts at an x-value of -2 and goes infinitely to the right, this is how you write its domain using an inequality.
What is x is greater than or equal to -2?
To find this measure of spread, you subtract the minimum value in a data set from the maximum value.
What is the range?
What subject does Mrs. G and Mr. Jamari want to teach?
What is Math and Music
State the equation of a line in slope-intercept form that has a y-intercept of (0, -7) and a slope of 2/3.
What is y = 2/3x - 7?
A correlation coefficient (r) close to this number indicates a very strong, near-perfect negative linear relationship.
What is -1?
If the graph of a horizontal line is y = 5, this is the range of the function.
What is 5 (or y = 5)?
This specific statistical value represents the middle 50% of the data and is found by subtracting Q1 from Q3.
What is the Interquartile Range (or IQR)?
How many Break Through Summers have Mrs. G and Mr. Jamari served?
What is 2 and 4?
If a line passes through (3, 4) and has a slope of -2, this is its y-intercept
What is 10?
True or False: If two variables have a strong correlation on a scatter plot, it proves that one variable caused the change in the other.
What is False? (Correlation does not equal causation!)
A vending machine sells sodas for $2 each. If you can buy anywhere from 0 to 5 sodas, this is the range of this discrete situation.
What is {0, 2, 4, 6, 8, 10}? (Must be listed as discrete values, not an inequality).
If a data distribution is skewed heavily to the right by a few massive outliers, this measure of center is usually better to use than the mean because it isn't pulled by the outliers.
What is the median?
Spell Mrs. G and Mr. Jamari's last name correctly?
What is Grefer and Ware?
