• Definition: A study that copies or is very similar to a previous study; replication of previous studies is done to add new knowledge (McMillan, 2012, pg. 36)
• Example: I could replicate a study done showing that homework is ineffective in improving students’ academic performance to confirm or disconfirm the theory.
2. Categorical Variable (McMillan pg. 41)
• Definition: assigns someone or something to a certain group based on certain characteristics (McMillan, 2012, pg. 41)
• Example: Some of the ways researchers categorize is based on age, gender, and grade.
3. Research Hypothesis (McMillan pg. 48)
• Definition: a statement made by the researcher that communicates what they think they will find (McMillan, 2012, pg. 48)
• Example: An example …show more content…
Sampling bias (McMillan pg. 112)
• Definition: when the researcher selects participants in order to have the outcome they want; choosing participants who will perform the way you need them to in order to get the results you need to support your theory (McMillan, 2012, pg. 112)
• Example: If a researcher were conducting a research study on the School to Prison Pipeline to see if there was a disproportion of black students being suspended for similar offenses and they only chose predominately black schools (a higher population of black students would show more black students being suspended).
9. Evaluation (McMillan pg. 118)
• Definition: using knowledge about something to make decisions regarding it (McMillan, 2012, pg. 118)
• Example: Time on task and student-teacher interaction is information used to evaluate if a teacher has effective classroom management.
10. Validity (McMillan pg. 131)
• Definition: when what is inferred is logical or reasonable and has evidence to back it up (McMillan, 2012, pg. 131)
• Example: They have to decide if the test given to students at the state level (FSA) is valid in measuring student achievement on the standards.
