Question
The executives at CBC want to realise how they are doing in ratings against the other networks as well as how the ratings will continue to change in the upcoming months. They likewise want to know if hiring stars makes a difference as well as the impact of fact based programming compared to hiring stars. You will create a PowerPoint presentation to solution the questions below. Reminisce that your audience is the management of CBC: Ensure your presentation is professional and provides sufficient explanation.
1. Descriptive statistics-
What is the average score for all CBC movies? How about ABN movies as well as BBS movies? Include a table that shows the average as well as the other descriptive statistics for the ratings of the three networks (one column for each network). Comment on which network is doing best as well as what you learn from the other key metrics in the table.
2. Charting-
Create a line graph of the monthly average ratings for CBC for the year. Note that there are multiple ratings data for the months, you will need to compute an average for each month as well as then plot the averages. After you make the graph, fit a linear trend line, showing the formula and the r-squared. Elucidate to the executives if you can use this time series data to forecast the ratings of upcoming months. How precise can you expect this forecast to be?
3. Hypothesis testing-
Must the CBC hire stars for their movies? To answer this problem, run a hypothesis test to understand if there is an important difference between the ratings of movies with stars vs. movies without stars. Use the data for CBC movies only. Use 95% confidence. Describe your answer- don't simply say yes or no without referring to the relevant figures.
4. Regression-
CBC Management has numerous questions- Which has more influence on a movie's rating- that it is fact based or that it has one star? How much does all of these factors change the ratings? Do you imagine a fact based movie that doesn't have any stars to get better ratings than a fiction movie with one star? Run a manifold regression where the dependent variable is ratings and the independent variables are star as well as fact. Use data from all networks not just CBC movies. How well does this regression examination illuminate the ratings? Validate your answers based on the results.
