Research Flashcards
What are the two main types of research?
Observational studies and Experimental studies
Observational studies
Collection of data by watching activities of subjects
Experimental study
studies that changes variables
Pure scientists
Scientists who study to learn knowledge
applied scientists
Scientists who study to solve problem
Deductive reasoning
Moves general to speesific to reseach a concllusion
Inductive reasoning
Moves spesific facts to a genearl to reaseve a conclution
Controlled exparment
here only one variable at a time is changed
Variable
Variabel is a condition in an exparement that is changed
Stratified random sample
The population is devided into groups of diffrent variables (ex. Ethnicity) then a random sample is taken form each group
Realiability
Would another similar study yeild similar results to first study
Validity
How well reasearch mesures to what it was supposed to mesure (how effective was it)
Quantititve measurement
Is mesure of how much
Mesurment
Mesurment that identifys things (ex.height or length)
Counting
Counting so counting objects in a category (ex.mean, median)
