statistics (term)
refers to a mathematical set of procedures for organizing, summarizing, and interpreting information
Population
the set of all the individuals of interest in a particular study.
Sample
a set of individuals selected from a population, usually intended to represent the population in a research study.
The relationship between a population and a sample.
a researcher studies a sample and then generalizes the results from the sample to the population.
Variable

The relationship between a population and a sample. | a researcher studies a sample and then generalizes the results from the sample to the population. |
Variable | a characteristic or condition that changes or has different values for different individuals. |
Datum | (singular) is a single measurement or observation and is commonly called a score or raw score. |
Data | (plural) are measurements or observations. |
Parameter | a value, usually a numerical value, that describes a population. A parameter is usually derived from measurements of the individuals in the population. |
Statistic | is a value, usually a numerical value, that describes a sample. A statistic is usually derived from measurements of the individuals in the sample. |
Descriptive Statistics | statistical procedures used to summarize, organize, and simplify data. |
inferential statistics | consist of techniques that allow us to study samples and then make generalizations about the populations from which they were selected. |
sampling error | is the naturally occurring discrepancy, or error, that exists between a sample statistic and the corresponding population parameter. |
Sampling error example | Because the characteristics of each sample depend on the specific people in the sample, statistics will vary from one sample to another. For example, the five students in sample 1 have an average age of 19.8 years and the students in sample 2 have an average age of 20.4 years. |
Relationships between Variables | Most research, however, is intended to examine relationships between two or more variables. |
correlational method | two different variables are observed to determine whether there is a relationship between them. |
