Introduction to Qualitative Research - IN terms of difficulty, how would you compare a content analysis approach to the study of social bias on television with a survey approach? In terms of useful information?
Which ratio would be best to compare three companies in terms of how well they are managing their expenses? Assume the three firms are in the same industry, produce similar products and are similar in nature to each other (ex: Nike vs Underarmour, etc...) (look through the below ratios in your notes/formula sheet/book so you understand what they are trying to measure) Multiple Choice Return on Equity Profit Margin Interest Coverage Ratio (Times interest Earned) Equity Multiplier
Compare the PE ratios of a couple of companies you are interested in. What does the comparison tell you? Was it surprising or what you would have expected?
1. The procedure specified DRY ice cubes. How would the results be impacted if the ice cubes had a film of liquid water on them? 2. The average initial temperature of the ice is assumed to be -15°C. How would the results be impacted if the average initial temperature of the ice was -10°C?
Estimate how much KE is there in an average size Helium balloon, the kind you would see at a kid's birthday party. If you could get all the molecules going the same direction, how fast would the balloon be going?
