Does the survey constitute an experiment or an observational study?
Sri K.
Determine whether an observational study or an experimental study was used. A study using college students was conducted to see if the percentage of males who pay for a date was equal to the percentage of females who pay for a date.
The Nature of Probability and Statistics
Experimental Design
Do women study more than men? We asked the students in a large first-year college class how many minutes they studied on a typical weeknight. Here are the responses of random samples of 30 women and 30 men from the class: (a) Examine the data. Why are you not surprised that most responses are multiples of 10 minutes? Are there any responses you consider suspicious? (b) Make a back-to-back stemplot to compare the two samples. Does it appear that women study more than men (or at least claim that they do)? Justify your answer.
