n Click the icon o view the scatterplot of average teacher pay and per pupil expenditures. From the scatterplot, is the correlation between average teacher pay and per pupil expenditure positive, negative, or near zero? he correlation is positive, because the scatterplot shows that as average teacher pay increases, the average per pupil expenditure tends to increase, and the regression line has a positive slope. What is the slope of the regression equation? Interpret the slope in the context of the problem. Select the correct choice below and fill in the answer be Type integers or decimals. Do not round.) O Average Teacher Pay and Average Per Pupil Expenditure DA. The slope is For each additional $1 in average per pupil expenditure in a state, the average teacher pay increases by an average of $. OB. The slope is For each additional $1 in average teacher pay in a state, the average per pupil expenditure increases by an average of $. 26000- Avg Per Pupil $ = - 6968 +0.342 Avg Teacher Pay 24000- 22000- 20000- 18000- 16000- 14000- 12000- 10000- 8000- 6000- 4000- 40000 4500 50000 5500 60600 6500 70600 7500 80000 8500 Average Teacher Pay Average Per Pupil Expenditure
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.
