100
When you observe the whole population instead of a small chunk of it. (Does not prove Causation)
What is an observation study?
100
This type of variable is a variable that you can count easily.
What is a discrete variable?
100
The average of the whole data set.
What is the mean?
100
This type of graph asses strength, direction, and form of a relationship.
What is a Scatterplot?
100
This function in your calculator is used to find an area in the normal distribution.
What is normalcdf?
200
This is when you cannot do a study on a full population, so instead you take a chunk out of the population to experiment on.
What is a Sample?
200
This type of variable is one that is hard to count, for example time.
What is a Continuous variable?
200
the middle of the entire data set.
What is the median?
200
This letter indicated how strong the relationship is between two variables; correlation.
What is "r"?
200
This calculation function is used to find a specific number or point in the normal distribution.
What is normalpdf?
300
This type of sampling method is when everyone in the study has an equal chance of being chosen.
What is Simple Random Sampling?
300
This type of data has two variables.
What is Bivariate Data?
300
A point that lies far off the normal points of the graph or distribution.
What is an Outlier?
300
a variable that is not included as an explanatory or response variable in the analysis but can affect the interpretation of relationships between variables. This variable can falsely identify a strong relationship between variables or it can hide the true relationship.
What is a lurking variable?
300
This type of distribution is a frequency distribution of the possible number of successful outcomes in a given number of trials in each of which there is the same probability of success.
What is a binomial distribution?
400
This type of bias occurs when the people in your study answer a survey question misleadingly or untruthfully.
What is Response Bias?
400
This type of frequency is the frequency that you get in the problem divided by "n"
What is relative frequency?
400
This type of graph easily displays the Q1 and Q3, and can easily see where the median and outlier is.
What is a box plot?
400
The linear fit that matches the pattern of a set of paired data as closely as possible. Out of all possible linear fits, this is the one that has the smallest possible value for the sum of the squares of the residuals.
What is a Least Squares Regression line?
400
This is when all probabilities fall between zero and 1.
What is a discrete distribution?
500
This is a group that gets a pill or any drug that will not do anything, to compare results with the people actually being tested.
What is a control group?
500
This type of graph measures the frequency of variables.
What is a histogram?
500
This statistic shows how far off on average the points fall away from the mean.
What is Standard Deviation?
500
a statistic that will give some information about the goodness of fit of a model. In regression, the ___ coefficient of determination is a statistical measure of how well the regression line approximates the real data points.
What is the Coefficient of Determination? (r squared)
500
This is when your data is symmetric and unimodal.
What is a normal distribution?
