Ethics
Withdrawal rights comes under which type of ethics?
Ethical Considerations/Guidelines
What is an advantage of case study?
1. high detail and rich in information
2. can incorporate other scientific methodology to collect data.
3. They allow phenomena.
Define qualitative data.
Non-numerical data and describes characteristics and qualities.
The experimenter makes a mistake when measuring the data.
Is what type of error?
Personal Error
Variables other than the IV that a researcher holds constant in an investigation, to ensure that changes in the DV are solely due to changes in the IV.
Defines which type of variable?
Controlled Variable
Ethical Concepts/Value requires the experimenter to do what?
The experimenter will need to consider and think about all the ethical concepts/values when they are creating their investigation/experiment.
type of investigation in which the causal relationship between two variables is tested in a controlled environment.
Describes which type of investigation design.
Controlled experiment
Factual data that is observed and measured independently of personal opinion.
Refers to which type of data?
Objective Data
Errors in data that are unsystematic and occur due to chance.
Defines which type of error?
Random error
Define Dependent Variable.
The variable that is measured to assess the effects of the IV.
Refers to the commitment to maximising benefits and minimising the risks and harms involved in taking a particular position or course of action.
What is this a definition of?
Beneficence
Observe and measure the potential relationship between two or more variables.
Describes which type investigation design.
Correlational Study
The higher the standard deviation means the data set is...
is further spread around the mean.
Refers to how closely a set of measurement values agree with each other.
Studying before school improves memory compare to studying after school.
What is the independent variable?
Studying before school or studying after school.
The researcher is able to answer the most insignificant questions about the research.
What type of ethics would this be?
Integrity
A psychology teacher made a brain out of paper to show their students what the brain looks like and where the different parts of the brain is found.
What type of investigation does this statement relate to?
Modelling
Refers to the extent to which consecutive measurements or studies produce the same results when carried out under identical conditions within a short period of time.
Is a definition of what?
Repeatability
Define Systematic Error.
Errors in data that differ from the true value by a consistent amount.
Compare extraneous variables and confounding variables.
extraneous variables are things that COULD have an impact on the DV whereas confounding variables are things what DID have an impact on the DV.
List the ethical considerations/guidelines.
withdrawal rights, informed consent, voluntary participation, debriefing, confidentiality, deception
Outline 1 disadvantage of simulation.
1. It can be time-consuming and expensive.
2. It is subject to programming and human error so may not always be an accurate prediction or reflection of reality.
If an experiment has low reproducibility what does this mean the experiment has?
Convenience sampling, extraneous variables, personal, random and systematic errors.
What does systematic errors effect and what does random errors effect?
Systematic Errors - Accuracy
Random Errors - Precision
Tess was doing an experiment to find out of students who meditate will get better marks on the next SAC.
The weather outside on the day may affect the results of students.
Which type of variable is this?
Extraneous Variable
