100

Type of observation where participants are aware of the fact that they are being observed.

What is 'overt observation'

100
Identify the DV in the following research question: Does caffeine increase attention span?
What is 'attention span'?
100
This is the type of hypothesis where one predicts that the IV will have an affect on the DV
What is research/experimental hypothesis?
100

This term refers to when a study measures what it is intended to measure.

What is validity?

100
Before beginning an experiment, researchers must obtain this from the participants.
What is 'informed consent'?
200

A type of experiment where the allocation into groups is not done randomly. Instead, some pre-existing inter-group difference is used. A major limitation is that no cause and effect relationship can be infered because we cannot be sure of the equivalence of comparison groups.

What is a 'quasi experiment'?

200
This is the variable that the researcher manipulates.
What is 'independent variable'?
200
These are the two conditions in an experiment.
What is 'control and experimental conditions'
200

This is what we call a combination of different approaches to collecting and interpreting data and it is used to enhance the credibility of a study.

What is 'triangulation'?

200
All participants have the right to this, meaning they can leave the experiment if they wish.
What is 'withdrawal'?
300

This is one other limitation of a correlational study other than not being able to establish a causation.

What is 'the third variable problem' (or other answers)?

300
This type of hypothesis says that the IV will have no affect on the DV.
What is 'null hypothesis'?
300
Define a) repeated measures design and b) independent groups design
What is a) The same participant is tested in both the control condition and the experimental condition. In other words, the same participant is tested twice. b) A comparison is made between two unrelated groups of participants. One group receives the experimental treatment and one group doesn’t.
300
This term refers to when a study reflects what happens in real life.
What is 'ecological validity'?
300
This is an ethical consideration in which the researcher does not tell the participants the true aim initially.
What is 'deception'?
400

This number for the correlation coefficient (effect size, r) shows researchers that  there seems to be a large correlation between two variables.

What means 0.50?

400

In this type of experiment the researcher has no control over the IV. Thus, the ecological validity is really high, but internal validity is low and researchers have less control over confounding variables.

What is a natural experiment?

400

In this type of experiment the study is carried out in the natural environment, but the researcher still manipulates variables.

What is Field experiment

400
This is the ability of a study to produce the same results if repeated multiple times.
What is 'reliability'
400

In research the aim is to be able to take our findings and generalize them to the larger population. Which is known as this.

What is 'generalizability'?

500

These are all methods the IB declares as a "research method".

What is the term summarizing the following: case sudy, observation (lab vs. naturalistic), interviews (unstructured, semi-structured, focus group), Experiments, Field experiments, Quasi-experiments, Natural experiments, Correlational research, Surveys?

500
a) Give the definition of Researcher Bias b) Give one remedy for this type of confounding variable
What is a) Errors in research that occur due to the personal motives and/or expectations of the researcher or research team. b) Standardization or Double-blind control
500

A problem with experiments is that if they are highly controlled and the environment is artificial, the study may have________

Low ecological validity

500

Name the type of validity: when an experiment was conducted using appropriate controls so that it supports the conclusion that the independent variable caused observed differences in the dependent variable.

Internal Validity

500

In this type of obervation, deception is part of the process. But deception mus always be kept to a minimum.

What is 'covert observation'?
