Discrete Random Variable
Random variables that take an interminably uncountable
number of potential values, regularly measurable amounts
Continuous Random Variable

variable together with their corresponding probabilities
Discrete Probability Distribution

variable and their corresponding probabilities
Mean of a Probability Distribution
Includes all of its elements from a set of data
Population
Consists of one or more data drawn from the population
Sample
A measure that is used to describe a sample
Statistic
Measurement or quantity that describes the totality of subjects
under consideration
Parameter

given equal chances to be chosen as part of the sample
Random Sampling
Single value that estimates the population parameter
Point Estimate
Range of interval used to estimate the population parameter
Confidence Interval
Applicable to use when the population is normal, sample
standard deviation is known and the sample size is less than
30
T-test
A decision-making process for evaluating claims about a
population
Hypothesis
