 To influence the public through collection of responses from random populations
 Characteristics
 Collection of information from a chosen sample
 Information collected by several different methods: phone, online, television, mail, personal contact
 Types may be cross sectional and longitudinal
 Advantages
 Ability to gather information on one particular question
 Disadvantages
 Validity of collected data depends highly on the methods for choosing the sample population and the way questions are asked
 Experimental research – a research method in which the researcher determines a question to be answered, develops a hypothesis, and collects data to determine the validity of the hypothesis
 Purposes
 To study specific factors and results of treatments on variables while controlling other variables
 To determine relations between variables
 Characteristics
 Only type of research that uses two variables
 Control (treatment) and results
 Only type of research that may attempt to influence a particular variable to attempt to prove the hypothesis
 Advantages
 Allows the study of many variables at once to understand interactions among them
 Control of conditions
 Disadvantages
 Control of conditions is often difficult
 Observational study – a method of research in which the researcher collects data by observing behavior or conditions and activities without influencing or interfering with that behavior
 Purposes
 To discover conclusions based on unbiased observation; to compare numerous variables
 To document information to be used in the future; to describe change
 Characteristics
 Observations done in natural environment or lab
 Observer may have direct or indirect contact with subject(s)
 Observation may be behavioral or nonbehavioral
 Advantages
 Provides information in a pure sense without intervention or influence
 Disadvantages

POPULATION MEAN OR POPULATION PROPORTION
Including, but not limited to:
 Population mean – mean of total collection of all elements of a set of data
 Sample mean – mean of a sample used to estimate the mean of a large population
 Formula for sample mean: , where n is the number of sample elements and a_{i} represents each sample element in the set. Verbally this is read as the sum of all the elements in the sample set divided by the number of elements in the sample set
 Population proportion – fraction of the number of desired outcomes in the collection of elements divided by the total number of elements in the collection
 Sample proportion – proportion of a sample used to estimate the proportion of a large population
 When a population is too large to count every element, a sample can be used to estimate the mean and the proportion of the population.
