Mr Jones students kept track of the hours that they studied the week previous to the test here the breakdown of the hrs studied and score x .20 6 9 18 4 5 12 y.95 45 55 90 22 30 70 .is this a positive, negative, no correlation. Find the equation of the line of best fit for data .what points are used to show the steps used to get equation. Using 2 points find the slope .once you find the slope use the point to substitute values to find b the equation should be y= mx +b. Use the equation to predict the scores for two people who studied 15 hrs and 9 hours ( hint substitute 15 in for x and 9 in for x you should have 2 answers. Was the datd correct yes or no.
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.
