What measures the effects of the independent variable?
In experimental research, the independent variable is manipulated or changed by
the experimenter
to measure the effect of this change on the dependent variable.
What is an idea arrived at logically from a theory it can be thought of as an educated guess and it can be tested?
A hypothesis
is a testable prediction that is arrived at logically from a theory. It is often worded as an if-then statement (e.g., if I study all night, I will get a passing grade on the test). The hypothesis is extremely important because it bridges the gap between the realm of ideas and the real world.

What is the purpose of Institutional Review Board (IRB)? The
purpose it to give ethical approval to the study.
What is the factor in an experiment that is changed by the experimenter?
The independent variable
is the the part of the experiment that the experimenter has direct control over. This variable is usually plotted on the y axis. Changes in the independent variable cause changes in other variables.
Why are independent and dependent variables important?
Dependent and independent variables are important
because they drive the research process
. … Dependent and independent variables are also important because they determine the cause and effects in research.
What is independent variable and dependent variable examples?
If you write out the variables in a sentence that shows cause and effect, the independent variable causes the effect on the dependent variable. … Example:
How long you sleep (independent variable) affects your test score
(dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
When conducting a naturalistic observation it is important that the researchers?
An advantage of naturalistic observation is that
it allows the investigators to directly observe the subject in a natural setting
. 1 The method gives scientists a first-hand look at social behavior and can help them notice things that they might never have encountered in a lab setting.
How do psychologists use the scientific method?
Psychologists employ the scientific method —
stating the question, offering a theory and then constructing rigorous laboratory or field experiments to test the hypothesis
. Psychologists apply the understanding gleaned through research to create evidence-based strategies that solve problems and improve lives.
How do psychologists use the scientific method to study behavior and mental processes?
Psychologists use the scientific method to
conduct their research
. The scientific method is a standardized way of making observations, gathering data, forming theories, testing predictions, and interpreting results. Researchers make observations in order to describe and measure behavior.
What is the purpose of the IRB quizlet?
Institutional review boards (IRBs) are
tasked with reviewing all studies involving human subjects to protect their rights and welfare
.
What are the primary responsibilities and priorities of the IRB?
The IRB is concerned with
protecting the welfare, rights, and privacy of human subjects
. The IRB has the authority to approve, disapprove, monitor, and require modifications in all research activities that fall within its jurisdiction as specified by both the federal regulations and institutional policy.
What is the IRB and what purpose does it serve quizlet?

any board, committee, or other group formally designated by an institution to review, to approve the initiation of, and to conduct periodic review of, biomedical research involving human subjects
.
When I change the independent variable I expect that?
It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable. A change in the independent variable directly causes
a change
in the dependent variable. The effect on the dependent variable is measured and recorded.
Which type of variable is being changed by the experimenter?
The independent variable
is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.
What variable can be changed manipulated?
A manipulated variable is
the independent variable
in an experiment. It’s called “manipulated” because it’s the one you can change.
What is the purpose of identifying variables in research?
Variables are important to understand because they are the basic units of the information studied and interpreted in research studies. Researchers
carefully analyze and interpret the value(s) of each variable to make sense of how things relate to each other in a descriptive
study or what has happened in an experiment.
What is the dependent variable what is being measured?
The dependent variable is
the variable that is being measured or tested in an experiment
. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
Why is it important in an experiment to distinguish between independent and dependent variables and why is it vital to control some variables?
Variables play an important part in psychology research. Manipulating an independent variable and measuring the dependent variable
allows researchers to determine if there is a cause-and-effect relationship between them
.
How do you determine independent and dependent variables?
An easy way to think of independent and dependent variables is, when you’re conducting an experiment,
the independent variable is what you change
, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
What would be the independent variable in an experiment?
The independent variable (IV) is the characteristic of a psychology experiment
that is manipulated or changed by researchers
, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
How do you identify independent and dependent variables in regression analysis?
The outcome variable is also called the response or dependent variable, and the risk factors and confounders are called the predictors, or explanatory or independent variables. In regression analysis,
the dependent variable is denoted “Y” and the independent variables are denoted by “X”
.
Why might researchers prefer using naturalistic observations when studying interesting variables?
Why might researchers prefer using naturalistic observation’s when studying interesting variables?
Observations reduce likelihood that participants will act differently because
they know they are being watched.
What is naturalistic observation in research?
Naturalistic observation is a
method that involves observing subjects in their natural environment
. The goal is to look at behavior in a natural setting without intervention. … Researchers may take notes or tallies of various behaviors they observe.
What is the importance of observation in research?
User research consists of two core activities: observing and interviewing. Since we’re most interested in people’s behavior, observing is the most important of these activities because
it provides the most accurate information about people, their tasks, and their needs
.
How can the term measures be best defined in the context of psychological research?
How can the term measures be best defined in the context of psychological research? are defined as
people’s written or oral accounts of their thoughts, feelings
, or actions. In , the answers are often open-ended and not constrained by the researcher.

Which core principle of the scientific method involves the assumption that simpler explanations of behavior are preferred?
The principle of simplicity or parsimony
—broadly, the idea that simpler explanations of observations should be preferred to more complex ones—is conventionally attributed to William of Occam, after whom it is traditionally referred to as Occam’s razor.
It is important to utilize the scientific method
to study psychological phenomena in an objective, empirical, and analytical way
. By employing the scientific method, researchers can see cause-and-effect relationships and generalize the results of their experiments to larger populations.
Which method is the most objective and scientific method used in psychology?
It is one of the most objective methods of collecting data. It facilitates accurate observations under controlled conditions. It helps in finding out the cause and effect relationship between two or more variables. The findings of the
experimental method
are verifiable.
