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.

A market researcher found a correlation between advertising budgets for fliers (a, in thousands of dollars) and sales (s, in thousands of dollars) at local stores of a national pharmacy chain. Linear regression produced the equation s = 25.4a + 4.5, with r = 0.57. A local pharmacy in the chain had sales of $875 000 with a flier advertising budget of $50 000. The store manager was concerned about the accuracy of the model. a) The manager should not be concerned because the model predicts this level of sales. b) The correlation coefficient indicates a moderate correlation, so variation should be expected. c) The correlation coefficient indicates a moderate correlation, so all predictions with the model will be inaccurate. d) The manager should be concerned

After conducting extensive market surveys, the research department provides the following estimates: • a weekly demand of 302 at a price of $14 per toaster • a weekly demand of 196 at a price of $17 per toaster The financial department estimates that weekly fixed costs will be $1,438 and variable costs (cost per unit) will be $5. Assume: • the relationship between price and demand is linear • the cost function in linear Use your models to predict the marginal profit when Yaster is producing and selling 265 toasters per week.

Flying twice as farA flight from Los Angeles to ABQ is about 2 hours but is 670.2 miles.A flight from San Jose to Chicago is 4 hours but is 1859.0 miles.Can anyone explain why the travel time from San Jose to Chicago is notlonger and closer to 5.75 hours?If the distance increase by 2, shouldnt the time increase by a factorof 2 as well?1. Write a linear model for this question. Takeoff and landing will take a fixed amount of time. Actualtravel in the air will take time proportional to the distance traveled. Think about which of thevariables (time and distance) is the independent variable, and identify the slope and intercept withtheir units.2. Use the data in the quotation to estimate the two constants in your linear model.
