Difference Between Hypothesis and Research Question

Terms in this set (69) The difference between a research question and a hypothesis is: a hypothesis attempts to answer the question posed by the research problem. Hypotheses must be consistent with an existing theoretical framework.

A research question is practice based, and a hypothesis is theory based. b. A hypothesis attempts to answer the question posed by the research problem.

• Hypothesis is a tentative prediction about the relationship between two or more variables.
• Research Question is the question a research study sets to answer.
• Hypothesis is predictive in nature.
• Research Question is inquisitive in nature.

The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

These two variables are used alongside each other, and a change in the independent variable will translate to a change in the dependent variable. That is, they are similar in the sense that they change at the same time. These changes may, however, occur in the opposite direction to each other.

A dependent variable is the variable being tested in a scientific experiment. The dependent variable is ‘dependent’ on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.

independent variable

An independent variable is a variable that represents a quantity that is being manipulated in an experiment. A dependent variable represents a quantity whose value depends on those manipulations.

The dependent variable is the variable that is being measured or tested in an experiment. In a psychology experiment, researchers are looking at how changes in the independent variable cause changes in the dependent variable.

Independent and Dependent Variable Examples

• In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score.
• You want to compare brands of paper towels, to see which holds the most liquid.

You can use a variable expression to describe a real world situation where one or more quantities have an unknown value or can change in value. To write a variable expression for a real world situation: Figure out which quantity in the situation is unknown and define a variable to represent the unknown quantity.

The use of random variables is most common in probability and statistics, where they are used to quantify outcomes of random occurrences. Risk analysts use random variables to estimate the probability of an adverse event occurring.

The standards overview for grades 3-5 expects the understanding that “in the ‘real-world,’ functions are mathematical representations of many input-output situations.” The user puts in money, punches a specific button, and a specific item drops into the output slot. (The function rule is the product price.
