Definition:

The subjects receiving the nonalcoholic drinks are the ____ group and are used in the study to minimize the influence of ____.​

What is control; the placebo effect​

200

Definition:

consists of the subjects who receive some special treatment in regard to the independent variable

What is experimental group?
200

Definition:

is a research strategy in which  subjects do not know whether they  are in the experimental or control groups

What is single-blind study? 
200

Definition:

are any measurable conditions, events, characteristics, or behaviors that are controlled or observed in a study

What is variables?

200

Correlational method is used for describing relations between two or more variables. Relations could be expressed as positive/negative strong/ weak. Hence coefficient of correlation could be +1, 0, -1 and all values between 0 and 1. 

Describe correlational method briefly. When do we use it?

200
I have designed a study where I look at the relationship between the number of children in a family and the family overall life satisfaction. I am doing a ____ research. My statistics will generate a number that indicates___ and ___ of the relationship. If I find a relationship of +.80, what does this tell me about the relationship?
What is correlational. The direction and the strength.
300

Definition:

is the variable that is thought to be affected by manipulation of the independent variable

What is dependent variable?
300

Definition:

which occurs when someone’s overall evaluation of a person, object, or institution spills over to influence more specific ratings

What is halo effect?
300

experiment, correlational method, naturalistic observation, case study, survey.

300

1. formulate a testable hypothesis, 2. select the method and design the study, 3. collect the data, 4. analyze the data and draw conclusions, 5. report the findings

Name the steps of scientific method. and describe them briefly.

400

Definition:

is a condition or event that an experimenter varies in 
order to see its impact on another variable

What is independent variable?
400

Definition:

occurs when a researcher’s expectations or preferences about the outcome of a study influence the results obtained

What is experimenters bias?
400

Definition:

is a research method in which the investigator manipulates a variable under carefully controlled conditions and observes whether any changes occur in a second variable as a result

What is experiment?
400

+1 is more than 0. 

+ means positive relation (variables go the same way)

- means negative relation (variables go the opposite way)

-.20; +.40, -.60, +.80

How do we measure the strength of the relationship? What does the sign (plus, minus) tell us? 

Rank the strength of these correlation coefficients: -.60; + -40, +.80, -.20-
