controlled experiment adv

• Controlled experiments can be repeated to gather more data and test the reliability of results.

• Controlled experiments are only conducted once to avoid bias.

• Controlled experiments do not require a hypothesis to be valid.

• Controlled experiments are only useful in theoretical studies.

controlled experiment

• an investigation that only considers one variable at a time

• an experimental investigation of the relationship between one or more IVs and a DV; all other variables are controlled.

• a study that does not require any control over variables

• an observation of natural phenomena without manipulation

repeatability

• is how close successive measurements of the same quantity are when carried out under the same conditions.

• is the ability to obtain consistent results over time regardless of conditions.

• is the degree to which a measurement can be replicated under different conditions.

• is the accuracy of a single measurement compared to a known standard.

internal validity

• refers to a study investigating what it sets out or claims to investigate.

• is the extent to which results can be generalized to other contexts.

• indicates the reliability of the measurement tools used in the study.

• is concerned with the ethical implications of the research conducted.

mixed design

• a combination of elements of within-subjects and between-subjects design

• a design that only uses within-subjects elements

• a design that only uses between-subjects elements

• a design that eliminates all variables

quantitative data

• data that includes measurable values and quantities

• data that is purely descriptive and non-numerical

• data that is collected through surveys and interviews

• data that cannot be compared on a numerical scale

within subjects design

• an experimental design in which participants complete every experimental condition

• a design where different participants are assigned to different conditions

• a method that involves random assignment of participants to conditions

• a design that compares different groups of participants at the same time

between subjects design

• an experimental design in which individuals are divided into different groups and complete only one experimental condition

• a design where all participants experience every condition

• a method that combines both experimental and observational techniques

• a design that focuses on the same group of individuals over time

random sampling

• selecting participants from the population in a way that means each member of the population has an equal chance of being selected to participate in the study

• choosing participants based on their availability and willingness to participate

• selecting participants who are most likely to provide useful information

• randomly assigning participants to different groups after selection

primary data

• data collected

  through first-hand research

  for an intended purpose

• data obtained from secondary sources

• data that is outdated and no longer relevant

• data that is collected randomly without a specific purpose
