is the complete collection of elements to be studied. | Population |
is a sub-collection of elements drawn from a population. | Sample |
are things that describe a sample’s contents. | Descriptive Statistics |
is making inferences about what sample data may indicate about a population | Inferential Statistics |
data can be separated into different categories distinguished by some non-numerical characteristic. | Qualitative |
data consists of numbers representing counts or measurements. | Quantitative |
data result from either a finite number of possible values or a countable number of possible values. | Discrete |
numerical data results from infinitely many possible values that can be associated with measurement error. | Continuous |
sampling is when members of the population are selected in such a way that each has an equal chance of being selected. | Random |
sampling is when you subdivide the population into at least two different sub-populations that share the same characteristics and then draw a sample from each subgroup. | Stratified |
are numbers that describe a population. | Parameters |
are numbers that describe a sample. | Statistics |
sampling is when you divide the population into sections and randomly select some of those sections, and then choose all the members from the selected sections. | Cluster |
