Which correlation coefficient is most likely to describe the relationship between brushing?

Which correlation coefficient is most likely to describe the relationship between brushing? The correct answer is: The correlation coefficient = -0.62. This is shown in the experimental studies.

Which of the following types of research is used to describe how strongly two variables are related?

Correlational studies are used to show the relationship between two variables. Unlike experimental studies however correlational studies can only show that two variables are related—they cannot determine causation (which variable causes a change in the other).

How can you describe the relationship between two variables?

Correlation is a statistical technique that is used to measure and describe a relationship between two variables. Usually the two variables are simply observed not manipulated. The correlation requires two scores from the same individuals. These scores are normally identified as X and Y.

What method is used to measure the strength of relationship between two or more variables?

correlation coefficient

The appropriate measure of association for this situation is Pearson’s correlation coefficient r (rho) which measures the strength of the linear relationship between two variables on a continuous scale.

Is a measure of the strength of the relationship between two variables psychology?

The correlation coefficient often expressed as r indicates a measure of the direction and strength of a relationship between two variables. … A correlation of -0.97 is a strong negative correlation while a correlation of 0.10 would be a weak positive correlation.

What are measurements that can be used to discuss the strength of the two variables and explain it?

Correlation is a statistical technique that is used to measure and describe the STRENGTH and DIRECTION of the relationship between two variables. Correlation requires two scores from the SAME individuals. These scores are normally identified as X and Y.

When two variables are correlated it means that quizlet?

When two variables are correlated it simply means that as one variable changes so does the other. How can one measure correlation? By calculating a statistic known as a correlation coefficient.

What does it mean to say that two variables are negatively correlated quizlet?

What does it mean to say that two variables are negatively​ associated? A. … There is a linear relationship between the​ variables and whenever the value of one variable​ increases the value of the other variable decreases.

What does it mean if two variables have a high correlation?

Correlation is a term that refers to the strength of a relationship between two variables where a strong or high correlation means that two or more variables have a strong relationship with each other while a weak or low correlation means that the variables are hardly related.

Which of the following correlation coefficients represents the strongest relationship?

-0.85

Answer: -0.85 (Option d) is the strongest correlation coefficient which represents the strongest correlation as compared to others.

What two things does a correlation coefficient represent?

What does the correlation coefficient indicate? The magnitude or amount of relationship and the direction of the relationship.

What does a positive correlation show?

A positive correlation is a relationship between two variables that move in tandem—that is in the same direction. A positive correlation exists when one variable decreases as the other variable decreases or one variable increases while the other increases.

What is a strong correlation?

The relationship between two variables is generally considered strong when their r value is larger than 0.7. The correlation r measures the strength of the linear relationship between two quantitative variables.

What is strong positive correlation?

Strong positive correlation: When the value of one variable increases the value of the other variable increases in a similar fashion. … Strong negative correlation: When the value of one variable increases the value of the other variable tends to decrease.

What are two characteristics of the scientific method?

Characteristics of scientific method
  • Unbiased. The great advantage of the scientific method is that it is unbiased. …
  • Falsifiable. For a scientific theory or hypothesis to be scientific it must be subject to an experiment and/or discovery that could prove the theory or hypothesis untrue. …
  • Reproducible.

How are variables related?

What do we mean by variables being related to each other? Fundamentally it means that the values of variable correspond to the values of another variable for each case in the dataset. In other words knowing the value of one variable for a given case helps you to predict the value of the other one.

What is the relationship between two variables in research?

A correlation is the measurement of the relationship between two variables. These variables already occur in the group or population and are not controlled by the experimenter. A positive correlation is a direct relationship where as the amount of one variable increases the amount of a second variable also increases.

What is the relationship between 1 and 2?

Enneagram Ones and Twos are a complementary couple since both offer the other the example of their own qualities. Both types are highly dutiful and are attracted to service roles and occupations: both may be teachers ministers or health care workers who have long hours and many responsibilities.

What is relationship measurement?

Measures of Relationship

Definition – are statistical measures which show a relationship between two or more variables or two or more sets of data. For example generally there is a high relationship or correlation between parent’s education and academic achievement.

How do you measure the relationship between two categorical variables?

To measure the relationship between numeric variable and categorical variable with > 2 levels you should use eta correlation (square root of the R2 of the multifactorial regression). If the categorical variable has 2 levels point-biserial correlation is used (equivalent to the Pearson correlation).

Which test measures the strength of the linear relationship?

The correlation coefficient

Definition: The correlation coefficient (r ) is a numerical measure that measures the strength and direction of a linear relationship between two quantitative variables.

Which of the following R values indicates the strongest relationship between two variables?

1 Expert Answer

A) 0.92 represents the strongest correlation. A correlation value r will always be between -1 and 1. The sign (+ or -) represents the direction while the numerical value represents the strength of the relationship between the two variables.

When a strong inverse relationship exists between two variables the correlation value tends to?

Inverse correlation tells you that when one variable is high the other tends to be low. Correlation analysis can reveal useful information about the relationship between two variables such as how the stock and bond markets often move in opposite directions.

What do you do when two variables are highly correlated?

The potential solutions include the following:
  1. Remove some of the highly correlated independent variables.
  2. Linearly combine the independent variables such as adding them together.
  3. Perform an analysis designed for highly correlated variables such as principal components analysis or partial least squares regression.

Which of the following is a measure of the strength of the linear?

A measure of the strength of the linear relationship between the two variables is called the Pearson correlation coefficient.

How do we determine the strength of a correlation quizlet?

A correlation also measures the “strength” of the relationship between X and Y. A correlation will have a value between -1 and +1. A correlation of 0 means that there is no relationship. A +1 means that there is a positive “perfect correlation” between two and a -1 means that there is a negative perfect correlation.

Which of the following measures is used to detect the strength of a relationship between nominal variables?

Crosstabulation (also known as contingency or bivariate tables) is commonly used to examine the relationship between nominal variables Chi Square tests-of-independence are widely used to assess relationships between two independent nominal variables.

What is an indication that two variables are strongly correlated quizlet?

What does it represent? The correlation coefficient r denotes the strength of a relationship between two variables it ranges from -1.0 to +1.0. The closer r is to +1 or -1 the more strongly the two variables are related.

When two variables are correlated it means that one is the cause of?

A correlation between variables however does not automatically mean that the change in one variable is the cause of the change in the values of the other variable. Causation indicates that one event is the result of the occurrence of the other event i.e. there is a causal relationship between the two events.

When two or more variables vary together they are said to be?

If variables are correlated what does this mean? This means that the variables vary together systematically that a change in one variable is associated with a change in the other.
