Question 1

Which of the following is TRUE about features of quasi-experimental research design?

Accepted Answer

Manipulation, but no control group or randomization

Answer

This answer is true because a quasi-experimental research design involves manipulation of the independent variable, but does not have a control group or randomization. In a quasi-experimental design, the researcher cannot randomly assign participants to groups, so they have limited control over the variables. However, they can still manipulate the independent variable to observe its effects on the dependent variable. Without a control group or randomization, it is difficult to establish a cause-and-effect relationship between the variables.

Question 2

Carry-over effects are related to:

Accepted Answer

Repeated measures design

Answer

Carry-over effects refer to the influence of a previous condition or treatment on the subsequent condition or treatment in a study. In a repeated measures design, the same participants are exposed to multiple conditions or treatments, allowing for the examination of carry-over effects. This design is particularly useful when studying within-subject changes over time or when controlling for individual differences. Therefore, the correct answer is repeated measures design.

Question 3

The extent to which it is possible to make an inference that the independent variable is truly influencing the dependent variable and relationship is not spurious, refers to:

Accepted Answer

Internal Validity

Answer

Internal validity refers to the extent to which a study can confidently attribute the observed effects to the independent variable, rather than to confounding factors or chance. It ensures that the relationship between the independent and dependent variables is not due to any other extraneous variables. In other words, internal validity ensures that the observed effects are genuine and not a result of random or spurious relationships.

Question 4

Which of the following is considered as a threat to internal validity of a research?

Accepted Answer

Maturation

Answer

Maturation refers to the changes that occur naturally over time in the participants of a study, which can potentially influence the results. These changes could be due to physical, psychological, or social factors that are unrelated to the independent variable being studied. Maturation is considered a threat to internal validity because it can confound the results by causing changes in the dependent variable that are not actually caused by the independent variable. This can make it difficult to determine if the observed effects are truly a result of the manipulation or simply due to natural maturation processes.

Question 5

Which of the following is NOT related to dealing with extraneous variables in a quantitative research?

Accepted Answer

Bracketing

Answer

Bracketing is not related to dealing with extraneous variables in quantitative research. Bracketing is a method used in qualitative research to acknowledge and minimize the researcher's biases and preconceived notions. It involves self-reflection and awareness of the researcher's own beliefs and perspectives. However, when it comes to dealing with extraneous variables in quantitative research, methods such as randomization, repeated measures, homogeneity, and blocking are commonly used to control and minimize their impact on the study's results.
