This and That
100
This type of graph can be used to show a frequency distribution for discrete data.
What is a bar graph?
100
This is used on a scatter plot to make predictions about the data being graphed.
What is a line of best fit?
100
Average
What is mean?
100
The average value a random variable tends to go towards after many repetitions of an experiment.
What is expected value?
100
Variables which cannot be measured numerically.
What is qualitative?
200
This type of graph shows trends of data over time.
What is a broken-line graph?
200
In this correlation, the scatter plot falls to the right.
What is a negative correlation?
200
The most frequent value in a set of numbers.
What is the mode?
200
Rolling a die a large number of times and recording the number on the top face should result in this type of distribution.
What is uniform?
200
In this type of sampling, the population is organized into groups and then entire groups are randomly selected.
What is cluster random sampling?
300
This type of graph shows the median and quartile values, as well as the spread of the data.
What is box-and-whisker plot?
300
In a set of data, the residual values will be very small.
What is a strong correlation?
300
The square of the standard deviation.
What is variance?
300
The probability of an event given that another event has already happened.
What is conditional probability?
300
A collection of chosen objects for which order does not matter.
What is a combination?
400
This shows the relationship between two variables and it can be strong or weak, positive or negative.
What is correlation?
400
The vertical distance between a data point and its line of best fit.
What are residual values?
400
(x - mean)/standard deviation
What is a z-score?
400
This operation calculates the number of ordered arrangements of n objects.
What is a factorial?
400
A triangular array of numbers that are the binomial coefficients that result from the Binomial Theorem.
What is Pascal's triangle?
500
This type of graph can be used to show a frequency distribution for continuous data.
What is a histogram?
500
A pattern of average behavior that occurs over time.
What is trend?
500
A standard distribution, such that the mean is 0 and the standard deviation is 1.
What is a standard normal distribution?
500
An ordered arrangement of objects selected from a set.
What is a permutation?
500
The number between 0 and +1 that gives the relative strength of the relationship between two variables.
What is coefficient of determination?
