Probability
Q: What is the only way to have 0% margin of error?
Ask everyone
Q: What does margin of error represent?
A: The precision of an estimate; smaller standard deviation = smaller margin of error; larger sample size = smaller margin of error
Q: What defines a “best survey”?
A: Random sample, random subjects, and random assignment

A: A trend line between points of data (used for prediction)
Q: What does standard deviation measure?
A: The amount of variability in a set
Q: What is the interquartile range (IQR)?
The difference between the third and first quartiles (Q3−Q1)
Q: What is the range of a data set?
A: The difference between maximum and minimum values
Q: What is the median?
A: The middle value of a numerically ordered set
Q: What is the formula for weighted average?
Q: What is an interval?
A: A range of numbers between two endpoints
Q: What is the mode?
A: The number in a set that appears most often
Q: What is frequency?
A: The number of times an event occurs
Q: What is the general form for absolute value equations?
y=a|x−h|+k
Q: What is the vertex form of a quadratic?
Q: What is the standard quadratic form?
Q: What is the quadratic formula?
Q: How do you find the x-coordinate of the vertex (max/min/symmetry)?
Q: What is the sum of quadratic solutions (roots)?
