Concept explainers

Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.

The arm span and foot length were both measured (in centimeters) for each of 20 students in a biology class. The computer output displays the regression analysis. Which of the following is the best interpretation of the coefficient of determination r2? About 37% of the variation in arm span is accounted for by the linear relationship formed with the foot length. About 65% of the variation in foot length is accounted for by the linear relationship formed with the arm span. About 63% of the variation in arm span is accounted for by the linear relationship formed with the foot length. About 63% of the variation in foot length is accounted for by the linear relationship formed with the arm span.

A pediatrician wants to determine the relation that exists between a child's height (x) and head circumference (y). She randomly selects 11 children from her practice and measures their height and head circumference in inches. She finds that the correlation is 0.527, and the regression equation is Y = : 0.223x + 9.68. What proportion of the variation in head circumference can be explained by the variation in the values of height? Round your answer to three decimal places. %

A pediatrician wants to determine the relation that exists between a child's height (x) and head circumference (y). She randomly selects 11 children from her practice and measures their height and head circumference in inches. She finds that the correlation is 0.653, and the regression equation is y = 0.226x + 4.86. What proportion of the variation in head circumference can be explained by the variation in the values of height? Round your answer to three decimal places. Hint: Make sure you give your answer as a percentage. %
Is there a relationship between the amount of protein (in grams) and the number of calories in items sold at fast-food restaurants? The scatterplot below shows the results of an analysis of 126 fast food items. For each item, the protein and calorie contents were measured. To predict number of calories based on protein content, the following regression equation was constructed: Predicted number of calories = 199.6 + 13.4 (grams of protein). Which one of the following statements is a correct interpretation of this equation? 4% of the variability in number of calories can be explained by the regression equation. If there are 0 grams of protein in a fast-food item, we predict there to be 13.4 calories in that item. As the number of calories increases by 1, we predict amount protein to increase by 199.6 grams. The correlation between number of calories and amount of protein must be 0.134. As amount of protein increases by 1 gram, we predict number of calories to increase by 13.4.…

A frequent flyer was interested in the relationship between dollars spent on flying and the distance flown. She sampled 20frequent flyers of a certain airline. She collected the number of miles flown in the previous year and the total amount of money the flyer spent. A regression line of distance flown on money spent was fit to the data, and the intercept and slope were calculated to be ?=24,000 b=10 . A person who spent $2000 is predicted to have flown: 44000.miles 34000miles 54000miles 24000miles
