Descriptive Statistics
This is the average of a set of numbers
What is the mean?
This operation is used to determine the probability of A or B occuring.
What is addition?
This bell-shaped curve is common in statistics.
What is Normal Distribution?
This interval estimates the range in which a population parameter lies.
What is a confidence interval?
This is the hypothesis that assumes no effect or no difference.
What is the null hypothesis?
This number is in the middle of an ordered data set.
What is the median?
This is the term for probability based on observed outcomes.
What is empirical probability?
The mean, median, and mode are equal in this type of distribution.
What is a symmetric distribution?
This test compares means for samples too small for a Z-Test.
What is a T-Test
The statistical significance of an event is determined by this value.
What is the p-value?
This measure shows how spread out the numbers are.
What is the standard deviation?
Events that cannot occur at the same time are called this.
What are mutually exclusive events?
This distribution shows the probability that a value will take one of two independent values under a given set of parameters or assumptions.
What is Binomial Distribution?
This test compares the means or probabilities between two groups
What is a Z-Test?
This term refers to data that lie far from other observations.
What is an outlier?
This is the difference between the highest and lowest values.
What is the range?
This operation is used to find the probability of events A and B occuring, given that they are independent events.
What is multiplication?
This is the number of independent values that can vary in a dataset.
What are degrees of freedom?
This type of error occurs when a true null hypothesis is rejected.
What is a Type I Error?
A correlation coefficient of 1 indicates a very strong type of this relationship.
What is a Linear Relationship?
This is the difference between the Q3 and Q1 values.
What is the IQR? (Interquartile Range)
The total probability of all possible events is always equal to this number.
What is 1? (or 100%)
This distribution measures the probability of success after a given number of trials.
What is Geometric Distribution?
This type of error occurs when a false null hypothesis is not rejected.
What is a Type II Error?
This value determines whether the null hypothesis is rejected or fails to be rejected.
What is the significance level?
