Why do psychologists use a systematic method to conduct research?
Psychologists use a systematic method in research in order to eliminate subjectivity and allow for consistency across studies. Stating that a scientific theory must be supported by empirical evidence means that the theory must be supported by testing it out through research.
What method do psychologists use to study behaviors?
Experimentation remains the primary standard, but other techniques such as case studies, correlational research, and naturalistic observation are frequently utilized in psychological research.
How is the scientific method used in psychological research?
In order to do this, psychologists utilize the scientific method to conduct psychological research. Researchers seek not only to describe behaviors and explain why these behaviors occur; they also strive to create research that can be used to predict and even change human behavior.
What comes first a hypothesis or theory?
In scientific reasoning, a hypothesis is constructed before any applicable research has been done. A theory, on the other hand, is supported by evidence: it’s a principle formed as an attempt to explain things that have already been substantiated by data.
What is least likely to occur after an experiment is conducted to test a hypothesis quizlet?
Which statement correctly compares a law and a theory? Both a law and a theory can be tested. Which is least likely to occur after an experiment is conducted to test a hypothesis? The hypothesis becomes a theory if the results support it.
Which situation would result in a theory being replaced rather than revised quizlet?
“New information is discovered that contradicts the existing theory” is the situation among the choices given in the question that would result in a theory being replaced rather than revised. so the answer would be New information is discovered that contradicts the existing theory.
What’s the difference between a hypothesis and a theory Brainpop?
What’s the difference between a hypothesis and a theory? “Theory is another word for “fact”; hypothesis is another word for “guess”. Theories have been confirmed through tests; hypotheses haven’t. Theories contain many hypothesis; a hypothesis only contains one theory.
Which statement best explains the difference between a law and a theory quizlet?
Terms in this set (62) Which statement best explains the difference between the law and the theory? A) A law is truth; a theory is mere speculation.
What are three possible controls for this experiment?
What are three possible controls for this experiment? Student answers will vary. Possible answers include, the ramp, the ball, the distance on the ramp from which the ball is released, the amount of air resistance, and so on.
Which statement best describes the difference between a law and a theory?
A law is a theory that has been proven to be true and universal A theory is a group of hypotheses that prove a law is true. A law is a statement of fact, but a theory is an explanation A theory is a proposed law that has not yet been peer reviewed.
Which type of graph is best for analyzing quantitative dependent and independent variables?
Bar graph – A bar graph shows the quantity of dependent variable verses the independent variable.
Which type of chart plots the relationship between dependent and independent variables?
X-Y (scatter) plot A scatter plot is often used to show relationships between independent and dependent variables. Instead of connected data points with a line, a best-fit line can be used to find a trend in data.
What is the independent variable in a pie chart?
The independent variable determines what slices are in the pie, and the response variable determines the sizes of the slices.
Does the independent or dependent variable come first?
Independent and dependent variables always go on the same places in a graph. This makes it easy for you to quickly see which variable is independent and which is dependent when looking at a graph or chart. The independent variable always goes on the x-axis, or the horizontal axis.
What is the relationship between an independent and a dependent variable?
The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Where does the dependent variable go in a hypothesis statement?
A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data. It may take the form of a cause-effect statement, or an “if x,…then y” statement. The cause is called the independent variable; and the effect is called the dependent variable.
