## Which of these R values represent the strongest correlation?

-0.85

Answer:

**-0.85**(Option d) is the strongest correlation coefficient which represents the strongest correlation as compared to others.## Which are value represents the weakest correlation?

-0.15

(a)

**-0.15**represents the weakest correlation.## Which of the following is not a possible value of the correlation coefficient?

The possible range of values for the correlation coefficient is

**-1.0 to 1.0**. In other words, the values cannot exceed 1.0 or be less than -1.0. A correlation of -1.0 indicates a perfect negative correlation, and a correlation of 1.0 indicates a perfect positive correlation.## What is R vs r2?

R: The correlation between the observed values of the response variable and the predicted values of the response variable made by the model. R

^{2}:**The proportion of the variance in the response variable**that can be explained by the predictor variables in the regression model.## Which of the following R values indicates the weakest relationship between two variables?

An r of

**+0.20 or -0.20**indicates a weak correlation between the variables. For example, Definition: linear correlation coefficient. A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables.. 2.3. 1 The strongest correlation is -0.8.## Which R value represents the strongest correlation quizlet?

When the r value is closer to

**+1 or -1**, it indicates that there is a stronger linear relationship between the two variables. A correlation of -0.97 is a strong negative correlation, while a correlation of 0.10 would be a weak positive correlation.## Which correlation is the weakest among 4?

The weakest linear relationship is indicated by

**a correlation coefficient equal to 0**. A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.## Which value of R represents data with a strong negative linear correlation?

−1

Strong positive linear relationships have values of r closer to 1. Strong negative linear relationships have values of

**r closer to −1**. Weaker relationships have values of r closer to 0.## What does the R value indicate in Pearson correlation quizlet?

The Pearson correlation coefficient, r, can take a range of values from +1 to -1. A value of 0 indicates that there is no association between the two variables. A

**value greater than**0 indicates a positive association; that is, as the value of one variable increases, so does the value of the other variable.## Which are value represents the strongest negative correlation?

-1.0

Negative correlation is a relationship between two variables in which one variable increases as the other decreases, and vice versa. In statistics, a perfect negative correlation is represented by the value

**-1.0**, while a 0 indicates no correlation, and +1.0 indicates a perfect positive correlation.## What does the sample correlation coefficient r measure which value indicates a stronger correlation r 0.918 or R − 0.932 explain your reasoning?

So the absolute value off zero 0.918 is 0.918 on the absolute value off negative 0.932 is 0.932 And now we see that the

**second value off our has a greater absolute value**, which, which means it has a new indication off a stronger correlation between two variables.## What are the possible range of values in correlation analysis quizlet?

The correlation coefficient, r, is a measure of the strength of a correlation. Its value can range only from

**-1 to 1**.## When would you use Pearson correlation to analyze quizlet?

When do you use Pearson’s (r) correlation? Pearson’s correlation is (most common correlation co-efficient) used

**when you want to find a linear relationship between two quantitative variables**. . Providing assumptions are met, Pearson correlation statistics can lead to strong / accurate estimates.## What is correlation investopedia?

Correlation is

**a statistic that measures the degree to which two variables move in relation to each other**. In finance, the correlation can measure the movement of a stock with that of a benchmark index, such as the S&P 500.## What is the value of R quizlet?

The value of r is

**between -1 and +1**. The value of r is a measure of the extent to which x and y are related. If all points in a scatterplot of a data set lie exactly on a downward-sloping line, what is the correlation coefficient? The correlation coefficient is r=-1 .## Which value of R indicates a stronger correlation R or R?

The correlation coefficient, often expressed as r, indicates a measure of the direction and strength of a relationship between two variables. When the r value is

**closer to +1 or -1**, it indicates that there is a stronger linear relationship between the two variables.
