Sciences - Unit 1 – TRU correctly

Statistics - correct answer ✔✔The term statistics refers to a set of mathematical procedures for
organizing, summarizing, and interpreting information.
Population - correct answer ✔✔A population is the set of all the individuals of interest in a
particular study.
Sample - correct answer ✔✔A sample is a set of individuals selected from a population, usually
intended to represent the population in a research study.
Variable - correct answer ✔✔A variable is a characteristic or condition that changes or has
different values for different individuals.
Data - correct answer ✔✔Data (plural) are measurements or observations.
Data Set - correct answer ✔✔A data set is a collection of measurements or observations.
Datum - correct answer ✔✔A datum (singular) is a single measurement or observation and is
commonly called a score or raw score.
Parameter - correct answer ✔✔A parameter is a value, usually derived from measurements of
the individuals in the population.
, Statistic - correct answer ✔✔A 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 - correct answer ✔✔Descriptive statistics are statistical procedures used to
summarize, organize, and simplify data.
Inferential statistics - correct answer ✔✔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 - correct answer ✔✔Sampling error is the naturally occurring discrepancy, or
error, that exists between a sample statistic and the corresponding population parameter.
Correlational method - correct answer ✔✔In the correlational method, two different variables
are observed to determine whether there is a relationship between them.
Experimental Method - correct answer ✔✔In the experimental method, one variable is
manipulated while another variable is observed and measured. To establish a cause-and-effect
relationship between the two variables, an experiment attempts to control all other variables to
prevent them from influencing the results.
Independent Variable - correct answer ✔✔The independent variable is the variable that is
manipulated by the researcher. In behavioural research, the independent variable usually
consists of the two (or more) treatment conditions to which subjects are exposed. The
independent variable consists of the antecedent conditions that were manipulated prior to
observing the dependent variable.
Dependent Variable - correct answer ✔✔Is the one that is observed to assess the effect of the
treatment.
