This measure of center is more resistant to outliers than the mean.
What is the median?
100
observed y - predicted y
What is the residual?
100
This phrase is used to describe an observed effect so large that it would rarely occur by chance.
What is statistically significant?
100
P(A|B) = P(A) and P(B|A)=P(B)
What are independent events?
100
This graph is used to illustrate the relationship between bivariate quantitative data.
What is a scatterplot?
200
To calculate, subtract the mean of the distribution from the observed x, then divide by the standard deviation.
What is the z-score (or standardized value)?
200
Measures the direction and strength of a linear relationship between two quantitative variables.
What is correlation (or r)?
200
randInt(1,9,3)
What is the calculator command for generating 3 random numbers from 1 to 9?
200
The type of variable where the probability distribution assigns probability as the area under the density curve above a specific interval.
What is a continuous random variable?
200
This graph shows the cumulative relative frequency of a particular quantitative variable.
What an ogive?
300
This rule helps to determine if data is normally distributed by checking the number of observations within each interval.
What is the 68-95-99.7 rule?
300
The fraction of the variation in the response variable that can be explained by variation in the explanatory variable.
What is the coefficient of determination (or r squared)?
300
This experimental design involves the random assignment of units to treatments which are carried out separately within each group of units known to be similar in some way that is expected to affect the responses.
What is block design?
300
Events that have no outcomes in common and can never occur simultaneously, for which the addition rule is used.
What are disjoint events (or mutually exclusive events)?
300
This family of graphs is strictly non-negative and has an area of 1.
What are density curves?
400
The square of the standard deviation.
What is the variance?
400
When this plot is random and scattered, there is evidence to suggest the linear model is acceptable.
What is the residual plot?
400
The 3 basic principles of experimental design.
What are control, randomize, and replicate?
400
1-P(none occur)
What is P(at least one)?
400
Mr. Loeffler doesn't like these graphs.
What are pie-charts?
500
This calculator command can be used to find the area under a normal distribution and above an interval.
What is normalcdf?
500
This value can be computed by r times the ratio of the response variable's standard deviation to the explanatory variable's standard deviation.
What is the slope of the least squares regression line?
500
The five steps of a simulation.
What are state/describe the problem, state assumptions, assign digits, simulate repetition, and state the conclusion?
500
The Law of Large Numbers
What law says that as the number of trials increases the proportion of occurrences of any particular event approaches its true probability of occurring?
500
A bar graph where the variables have been divided into sub-groups
