Research Methods
What are the 6 research Methods we learned about?
Naturalistic observation, Case studies, Laboratory Observation, Testing, Surveys, Longitudinal Method/ Cross Sectional Method
What is the first step of the observation Method?
Observation
What is the Variable that the researcher controls?
Independent Variables
When a person’s health improves after taking a fake treatment is called the...
Placebo Effect
What is a measure of how closely one thing is related to another?
Correlation
What are the disadvantages of the Naturalistic observation Method?
Researchers have no control. Cannot determine why subjects make certain choices.
What is a hypothesis?
testable prediction
Example: People with low self esteem score higher on a depression scale
What is the variable that may change in response to the independent variable
Dependent Variable
participants don’t know whether they are receiving the treatment or not. This is an example of what kind of study?
Single Blind Study
What type of correlation has one thing go up while the other goes up?
Positive Correlation
What are the disadvantages of the case study method?
Too narrow of a scope. Only look at one case and try to apply to others.
For a hypothesis to become a theory, what needs to happen by others first?
Replication
What is the Independent Variable?
George Donald the Third wants to see how studying impacts his grades. He tracks the number of hours (h) he spends studying for each weekly math quiz and records his final score (s) out of 100 points. As he increases his study time, his quiz score changes.
Hours Studying
How should participants be assigned positions in an experimental study. Assigning experimental group and the control group.
Random Assignment
What type of correlation has one thing go down and the other goes down as well?
Negative Correlation
What are the advantages of Laboratory observation method?
Enables researchers to conrtol certain aspects of the study.
What ways can someone test their hypothesis?
Create an experiment/other research method
What is the control Group?
Stephen Steven Stefanson is testing a new liquid fertilizer to see if it makes his tomato plants grow faster. He takes five identical tomato plants and gives them different amounts of fertilizer each week: 0 mL, 5 mL, 10 mL, 15 mL, and 20 mL. After four weeks, he measures the total height of each plant in centimeters.
the plant given 0ml
participants & researchers are unaware of who has obtained the treatment. This is an example of whatkind of study?
Double Blind Study
Does Correlation Imply Causation?
NO
What is the difference between Cross sectional method and Longitudinal method?
Cross sectional:select similar sample of different ages, and compare behaviors of the different age groups
Longitudinal Method:Researchers select a group of participants & observe over time, often very long
What is the tendency to believe after learning an outcome, that one would have foreseen it?
Hindsight Bias
What is the dependent variable?
Frank Furter Mcfurterson opens a gourmet hot dog stand at a local park. He wants to know if lowering his prices will help him sell more hot dogs. Over five Saturdays, he changes the price of a standard hot dog to $6, $5, $4, $3, and $2. At the end of each day, he records the total number of hot dogs sold.
The Number of Hotdogs sold
What examines assumptions, discerns, hidden values, evaluates evidence and assess conclusions. This is required when performing any type of experiment.
