Question 23 5 points Save Answer Question B-3: Application Question (Video Game Ratings) Below is the adapted analysis result from one of my recent research projects. In this study, I collected consumers' online reviews on several online video games. To be more specific, these are Multiplayer Online Role-Playing Games (MORPG), such as 'World of Warcraft.' To play an MORPG, players usually need to purchase an installation CD first and to pay a monthly subscription fee. They can register accounts on this MORPG's website and create their own avatars in the game's virtual world. Players can then explore the virtual world joined by millions of other subscribers, and build up their avatar's power to advance in the game. Most often, they need to team up with other players to complete a quest simultaneously in an MORPG. In the regression analysis, the dependent variable is RATING, which is consumer's overall rating on a specific game. The independent variables include: " NUMUSERS: The number of total users of the specific game when the review was posted " GRAPHICS: The reviewer's evaluation of the game's graphics attribute (larger number represents better Graphic system) SOUND: The reviewer's evaluation of the game's sound attribute (larger number represents better Sound system) DIFFICULT: The reviewer's evaluation of game's overall difficulty level (higher number means that the game is more difficult) ' DIFFICULT_SQUARE: The square term of DIFFICULT to capture the quadratic effect " MONTHFEE: The monthly subscription fee of the game in USD " CDPRICE: The price of the installation CD of the game in USD ' TIMESPENT: The number of hours the reviewer spent playing the specific game till he/she posted the review Dependent Variable = Individual RATING Explanatory Variable Coefficient Estimate (S to Error) NUMUSERS 0.068*$ 3 (0.02) GRAPHICS 0.40* (0.03) SOUND 0.36** (0.02) DIFFICULT 2.29+ (0.19) DIFFICULT_SQUARE -037* (0.03) MONTHFEE -0.10 (0.10) CDPRICE 0.06*# (0.01) TIMESPENT 0.1 1* * (0.03) INTERCEPT 0.84 (1.60) Model R2=74.2%; Adj R2=73.98%; F =329.62*** Note: * p
