continuous.Which of the following are suitable hypotheses?Potential Hypothesis: Can people with long arms throw further than people with short arms?This is not a valid hypothesis as it is presented as a question rather than as a statement. “People with long arms can throw further than people with short arms” would be a validhypothesis, and one that could be reasonably tested. Both variables are numerical, and
both are continuous. Data can be collected easily once a set of parameters are chosen. What will people throw? How many chances will they get? Are they allowed to have a runup? Etc. Potential Hypothesis:People prefer McDonalds to Burger King.This is not a suitable hypothesis for investigation in this course. There is only one variable; the restaurant, and it is qualitative. (Not numerical). If this was an area you wanted to investigate, a suitable hypothesis might be “Younger people eat more frequently at fast-food outlets”. This hypothesis involves tow quantitative variables; age and frequency of fast-food outlet visits. Again, parameters would need to be clearly defined. Are you going to count the number of visits, or ask about the food consumed?Potential Hypothesis:Girls are better at Mario Kart 7 than boys.This is a valid hypothesis, but would not be suitable for this course, as although there aretwo variables (gender and standard at Mario Kart however, you might choose to measure that), only one of them is qualitative. This would restrict the analysis you wouldbe able to do and would not give you the chance to demonstrate your understanding of some of the more advanced processes that are encountered later in the course.
