When the relationship between two or more independent variables needs to be tested, a common tool to use is a regression analysis. Take, for example, a study that shows the relationship between gaming and teen violence or a study that shows a correlation between fast-food eating habits and obesity. Complete the following for this assignment

Describe 2–3 combinations of independent and dependent variables that you could test using a regression analysis.

What types of results could the regression analysis yield? How could you use the knowledge gained from the test?

Describe a specific organizational application of correlation and regression that you will use in your future career.

Describe a situation in your current or former workplace for which it would be appropriate to use correlation and regression to predict a future outcome that the company may be interested in. If you do not have an example for your workplace, please substitute a company that you are familiar with instead.

Why do you believe it is important for the company to look at these variables? What does the company risk if it does not do this correlation/regression?

Answer

  • There could be different kinds of relapse examination. It could be a direct relapse where the relationship is relied upon to be between one free factor and one ward variable. It could likewise be a various relapse where the needy variable is affected by numerous free factors. A portion of the models are
  • Number of units sold (subordinate variable) on ad spending plan (autonomous variable)
  • Farming yield of the district (subordinate variable) on soil organization (free factor), downpour measure (autonomous variable), span of the planting, collecting, (autonomous variable)
  • Relapse examination demonstrates the connection among circumstances and logical results. They help in understanding how much a variable effects the outcome or a result. It likewise enables associations and analysts to assess their theory on different business parameters.
  • Utilizing the information of the factors, their effect on the result and the general connection, we can settle on basic business choice, for example, designation of asset, spending plan, exertion, and improve the general likelihood of accomplishment in any business crusade.
  • Each association estimates the profitability of their worker. One of the particular application that can utilize connection and relapse strategy is to relate the profitability of the representative with a few free factors, for example, instruction, age, sex, and social foundation.
  • At the present work environment I function as a showcasing administrator. Normally one of my obligations include dealing with the limited time spending plan. Relapse investigation enables me to decide the accomplishment of the promoting effort (reach, presentation, and so forth.) by a few autonomous factors, for example, (channels, spending plan distributed, timing of the advertisements, and so forth.). These investigations can enable me to draw an expected pattern line that will enable me to comprehend the effect of these distinctive notice and limited time channels and how their effect will be later on.

A measure of the strength of the linear relationship that exists between two variables is called: Slope/Intercept/Correlation coefficient/Regression equation. If both variables X and Y increase simultaneously, then the coefficient of correlation will be: Positive/Negative/Zero/One. If the points on the scatter diagram indicate that as one variable increases the other variable tends to decrease the value of r will be: Perfect positive/Perfect negative/Negative/Zero. The range of correlation coefficient is: -1 to +1/0 to 1/-∞ to +∞/0 to ∞. Which of...
