Q

Quasi-Experiments definition:

A

Quasi-experiments are research designs that allow researchers to evaluate the effects of treatment without random assignment to groups. Researchers take advantage of naturally occurring differences in groups to study the effects of variables.

80
Q
A
81
Q

Purpose of Quasi-Experiments

A

Quasi-experiments are often conducted in natural settings, allowing researchers to study interventions in more realistic environments (e.g., schools, hospitals, or communities

In situations where random assignment could pose ethical issues (e.g., assigning individuals to potentially harmful conditions)

Researchers may face practical limitations that make random assignment difficult, such as logistical challenges, resource constraints, or the nature of the groups being studied (e.g., existing classes in a school)

82
Q

Cons of Quasi-Experiments

A

More exposure to confounding variables which threatens validity of experiment and Selection Bias(differences between groups could influence the outcomes)

Also doesn’t give as much control as true experiment

83
Q

Quasi-experiments are valuable in situations where random assignment is not feasible, such as studying the impact of trauma on individuals.

Why is Random Assignment not feasible

A

Ethics

84
Q

Independent Variable: Used in experiments, the factor that is being ______. This is the _____

A

MANIPULATED, CAUSE

85
Q

Dependent Variable:
Used in experiments, the factor whose outcome is ________. This is the ____

A

MEASURED, EFFECT

86
Q

Confounding Variable

A

An outside variable, that you aren’t trying to measure or test that may skew the results

87
Q

Confounding variables can make it hard to ________ the true relationship between the independent and dependent variables, making it difficult to determine if the observed effects are due to the independent variable or the confounding variable.

A

Can make it hard to UNDERSTAND the true relationship

88
Q

Cons of Experimental: Not always can be done because it would be unethical or impractical

A
89
Q

Validity

A

The extent to which a test, measurement, or research study accurately measures what it claims to measure. It tells us whether the results are accurate and meaningful.

90
Q

A
93
Q

Is the following experiment reliable or valid or both?

Every time a mouse goes on the scale it says that the mouse weighs 600 lbs.

Experimental - Only type of study that can prove _____

A

95
Q

Double-Blind Procedure Definition:

96
Q

Double-Blind Procedure is commonly used in ?

A

Drug evaluation Studies

97
Q

Experimental methods allow researchers to ______ variables, use ______ groups, and apply ______ __________ to establish _______ & ______ relationships.

A

Experimental methods allow researchers to MANIPULATE variables, USE CONTROL GROUPS, and apply RANDOM ASSIGNMENT to establish CAUSE & EFFECT relationships.

98
Q

Placebo definition:

A

A placebo is a substance that has no effect, often used as a control in clinical trials. Placebos are designed to look identical to the active treatment but do not contain any active ingredients.

99
Q

Placebo Effect:

A

The placebo effect refers to the phenomenon where a person experiences a real improvement in their condition after receiving a treatment that has no therapeutic effect, simply because they believe they are receiving a genuine treatment.

100
Q

Nocebo Effect:

A

Expectation of negative effects of a treatment, even when it doesn’t do anything, increases the chance that people will feel them

101
Q

Both the Placebo and Nocebo effect are ____________ ______

A

Confounding Variables

102
Q

A

BLIND

The CLOSER to ends of the range the STRONGER the correlational coefficient. The sign of the coefficient does NOT matter towards the strength, it only shows DIRECTION of the relationship. The closer to 0, the weaker the correlational coefficient is. (POSTIVE SIGN = POSTIVE CORRELATION) (NEGATIVE SIGN = NEGATIVE CORRELATION) (NUMBER CLOSE TO 0 = NO CORRELATION)

147
Q

Conformation Bias:

A

the tendency to seek out and prefer information that supports our preexisting beliefs

148

A

Conformation Bias

149
Q

Illusory Correlation definition and how it is caused

A

Because of conformation bias people sometimes perceiving a relationship between variables when there isn’t or perceiving a stronger/weaker relationship (often arising from chance events) then there is (before looking at the data)

150
Q

Regression Mean - A _____ phenomenon that occurs when ______ measurements are followed by more _____ results

A

A STATISTICAL phenomenon that occurs when EXTREME measurements are followed by more TYPICAL results

151
Q

What is this the representing:

If a variable is unusual on its first measurement, it tends to be closer to the average on a second measurement.

A

Regression towards the mean

The coach might think because he yelled they did better but its really because of regression toward mean.

152
Q

If a team does terrible one game and the coach yells at them and the next game they go back to good playing. They are regressing towards the ____

A

mean (however Regressing to mean doesn’t happen only from low values but also high values.

153
Q

This is a definition of ______
These methods go beyond correlation to demonstrate the actual effects one variable has on another.

A

Experimental Methods

154
Q

Third Variable Problem: A situation in correlational research where a third, unmeasured variable causes the relationship between two other variables, making it appear that there is causation when there isn’t.

A
155
Q

All cause and effect relationships are correlational but not all correlational relationships are cause and effect

True or False

A

True

156
Q

Researchers find a correlation between students’ time spent playing video games and their academic performance. As students spend more time playing video games, their grades tend to be lower.

Question: What might explain this correlation, and what is the third variable?

A

While it appears that playing video games negatively affects academic performance, a third variable, such as time management skills, could be influencing both. Students who struggle with time management might spend more time gaming and less time studying, leading to lower grades. In this case, time management is the third variable that explains the correlation without implying that video games directly cause poor academic performance.

157
Q

Causational relationships between variables are/aren’t always correlational

A

CAUSATIONAL ARE ALWAYS CORROLATIONAL

158
Q

Correlational Relationships are/aren’t always Causational

A

Correlational Relationships ARE NOT always Causational

159
Q

unclear WHICH variable is influencing the other

160
Q

What is this the definition of?
when two variables are correlated, it’s difficult to determine whether Variable A causes changes in Variable B, or if Variable B causes changes in Variable A.

A

Directionality Problem

161
