Question 1

2 types of non experimental research:

Answer 1

correlational and observational

Question 2

experimental research is high in internal validity, correlational research is low
in internal validity, and quasi-experimental research is:

Answer 2

in between

Question 3

correlational research involves measuring:

Answer 3

2 variables and assessing the relationships between them with no manipulation of an independent variable

Question 4

correlation does not imply:

Answer 4

causation

Question 5

While correlational research cannot be used to establish causal relationships between
variables, correlational research does allow researchers to

Answer 5

establish reliability and validity, providing converging evidence, describing relationships, making predictions

Question 6

Correlation coefficients can range from and what does the sign indicate?

Answer 6

-1 to +1. direction of the relationship between the variables and the numerical value indicates strength of relationship

Question 7

Researchers often use complex correlational research to

Answer 7

explore relationships among several variables in same study

Question 8

Complex correlational research can be used to explore

Answer 8

possible casual relationships among variables using techniques such as partial correlation and multiple regression

Question 9

partial correlation and multiple regression can show:

Answer 9

patterns of relationships that are consistent with some causal interpretations and inconsistent with others

Question 10

qualitative research generally involves:

Answer 10

asking broader research questions collecting more detailed data such as interviews, and using non statistical analysis

Question 11

Many researchers conceptualize quantitative and qualitative research as

Answer 11

complementary and advocate combining them. ex qualitative research can be used to generate hypotheses and quantitative research to test them

Question 12

There are several different approaches to observational research including

Answer 12

naturalistic observation, participant observation, structured observation, case studies, and archival research

Question 13

Naturalistic observation is used to observe people in their

Answer 13

natural setting

Question 14

participant observation involves becoming an

Answer 14

active member of the group being observed

Question 15

structured observation involves

Answer 15

coding a small number of behaviors in a quantitative manner

Question 16

case studies are typically used to

Answer 16

collect in depth info on a single person

Question 17

archival research involves

Answer 17

analyzing existing data
