Study Notes
- Statistics is the science of collecting, analyzing, and interpreting data.
- Descriptive statistics summarizes data in a convenient form, while inferential statistics makes generalizations about a larger set of data.
- Experimental units are objects on which data is collected, while populations are sets of units being studied.
- Variables are characteristics or properties of experimental units.
- Samples are subsets of populations used when measuring the variable for each experimental unit is not possible.
- Statistical inference is an estimate or prediction about a population based on information contained in a sample.
- Reliability is a measure of the degree of uncertainty associated with a statistical inference.
- Descriptive statistical problems involve investigating variables in a population or sample.
- Inferential statistical problems involve making inferences about a population based on information contained in a sample.
- Both types of statistical problems involve identifying patterns in data.
