Total questions: 20
Worksheet time: 11mins
which of the following describes aim? (CHOOSE ALL THAT APPLY)
a single statement that describes the purpose or reason for why we are conducting an experiment
should be brief and concise
state the purpose of the experiment
written before a study is run
What is a hypothesis?
predicts the findings of a study. It is written before the study is run
a statement predicting the direction of a relationship between variables.
a statement predicting that one variable will be related to one another but it won’t state in which direction
results obtained were due to chance and not the independent variable that the researcher changed or the situation that they engineered
What is a directional hypothesis?
predicts the findings of a study. It is written before the study is run
a statement predicting the direction of a relationship between variables.
a statement predicting that one variable will be related to one another but it won’t state in which direction
results obtained were due to chance and not the independent variable that the researcher changed or the situation that they engineered
What is a non directional hypothesis?
predicts the findings of a study. It is written before the study is run
a statement predicting the direction of a relationship between variables.
a statement predicting that one variable will be related to one another but it won’t state in which direction
results obtained were due to chance and not the independent variable that the researcher changed or the situation that they engineered
What is a null hypothesis?
predicts the findings of a study. It is written before the study is run
a statement predicting the direction of a relationship between variables.
a statement predicting that one variable will be related to one another but it won’t state in which direction
results obtained were due to chance and not the independent variable that the researcher changed or the situation that they engineered
Operationalize Variables?
It is expected to be responsible (cause) for changes in the dependent variable
the factor under investigation in an experiment which is manipulated to create two or more conditions.
Put into measurable form
Researcher manipulates the IV to produce two or more conditions
Independent Variable (IV)?
a variable which either acts randomly, affecting the DV in all levels of the IV, or systematically, so it can obscure the effect of the IV, making the results difficult to interpret
the factor in an experiment which is measured and is expected to change (effect) under the influence of the independent variable.
the factor under investigation in an experiment which is manipulated to create two or more conditions.
Any difference in the number of words spelt correctly (out of 25) of females compared to males is due to chance.
Dependent Variable (DV)?
a variable which either acts randomly, affecting the DV in all levels of the IV, or systematically, so it can obscure the effect of the IV, making the results difficult to interpret
the factor in an experiment which is measured and is expected to change (effect) under the influence of the independent variable.
the factor under investigation in an experiment which is manipulated to create two or more conditions.
Any difference in the number of words spelt correctly (out of 25) of females compared to males is due to chance.
Extraneous Variable?
a variable which either acts randomly, affecting the DV in all levels of the IV, or systematically, so it can obscure the effect of the IV, making the results difficult to interpret
the factor in an experiment which is measured and is expected to change (effect) under the influence of the independent variable.
the factor under investigation in an experiment which is manipulated to create two or more conditions.
Any difference in the number of words spelt correctly (out of 25) of females compared to males is due to chance.
an investigation looking for a causal relationship in which an independent variable is manipulated and is expected to be responsible for changes in the dependent variable is?
independent variable
an experiment
in a lab
control
research method in which there is an IV and DV and strict controls. Looks for a causal relationship and is conducted in a setting that is not the usual environment for the participants with regard to the behavior they are performing.
Lab Experiment
Field Experiment
Natural Experiment
Stimuli
an investigation looking for a causal relationship between the IV which is manipulated and is expected to be responsible for the changes in the DV. It is conducted in the normal environment for the participants for the behavior being investigated
Lab Experiment
Field Experiment
Natural Experiment
Stimuli
an investigation looking for a causal relationship in which the IV cannot be manipulated by the experimenter. Instead they are studying the effect of the existing difference.
Lab Experiment
Field Experiment
Natural Experiment
Stimuli
These involve a detailed study of an individual, event or an institution and it uses information from a range of sources; including the person concerned, colleagues, friends and family. A number of research methods may be used such as observation and interviews. They are often also longitudinal in nature
Learning Approach
Case Study
Natural Study
Social Approach
the way in which participants are allocated to levels of the IV
Research method
Research Design
Repeated Measures
Independent Measures
each participant performs in every level of the IV. Participants repeat their performance under different conditions
Research method
Research Design
Repeated Measures
Independent Measures
a different group of participants are used for each level of the IV (condition)
Research method
Research Design
Repeated Measures
Independent Measures
participants are arranged into pairs. Each pair is similar in ways that are important to the study and one member of each pair performs in a different level of the IV
Matched pairs
Research Design
Repeated Measures
Independent Measures
The participant gives the researcher information about themselves directly
Matched pairs
Research Design
Self Report
Independent Measures
Ways someone can self report (select all that apply)
Questionnaire
Interview
Scientific observation
EKG
