area study 3 sac formative booklet Flashcards
population

sample
the participants selected from the population who participate in the investigation
investigation aim
the purpose of the study
includes the variables IV and DV being studied and is written as a statement
independent variable
the cause of the change
dependant variable
the measure of the change

involves defining how they will be manipulated or measured in the experiment (or other investigation).
how to structure a hypothesis
begins with:it is hypothesized that
IV experimental group
strength or direction (lowered or increased)
DV
comparison (compared to)
IV control group (those who did not…)
hypothesis
a statement predicting the probable outcomes of an investigation
experimental group
the participants that are exposed to the IV
control group
those who are not exposed to the IV
random errors
Random errors are errors due to some chance factor or chance variation in a measurement
what do random errors reduce
precision of measurement
systematic errors
Systematic errors are produced by some factor that consistently favours one condition rather than another
what do systemic errors reduce
accuracy of measurement
personal errors
Personal errors are faults entirely sourced from the researcher, which is why they are also called human errors. Include mistakes and miscalculations
