Problem 1

Use the Internet to find a menu with dietary information such as fat or calorie content per menu item. Create a review of the restaurant that includes a box and whisker plot to support your claims about the general healthiness of venue.

Include a link to the menu information you found, the data you're using, a box and whisker plot, and an analysis of the box and whisker plot to support your review or the restaurant.

Problem 2.

At a high school prom, 274 out of 448 students voted for queen. This is a decrease from last year when 322 students voted. Assume the same number of students were eligible to vote for prom queen both years.

What is the percentage of students who voted this year?

What is the percentage of students who voted last year?

What is the percent change? (Be careful!)

Problem 3

Graph the following data set in such a way that

1. it emphasizes change
2. it emphasizes little or no change

Reggie loves to take the SAT . He decides to take it as many times as possible.

His scores in order of trial are 1020, 1050, 1100, 1130, 1120, 1140, 1160, 1174

Problem 4

Find 5 graphs and explanations. Summarize the information given of each of the five graphs separately and independent on each other. Provide an alternate explanation using the same data. Re-graph the information for each in a different way, and provide a different analysis of the data. Explain why the information given is irrelevant.

Problem 5

Choose 2 of the following clips from the CBC Archives. Summarize the bias in each clip.

If a researcher intentionally includes a bias so their report is misleading, then he or she would be guilty of unethical statistical practice.

You may also wish to explain that all media has a bias, or a point of view it supports. As ideas change over time, historical media can seem to have a more negative bias.

You will be viewing archival material to identify bias and stereotyping. Bias may be shown by what is said, what is not said, and what is implied. Bias is also important to keep in mind when doing a statistical study. Sometimes, the bias is due to the participants. For example, when asked how many hours students studied for a test on a survey from their teacher, they may tend to round up so they look like more active students. This would make the results biased. In an Internet survey where people chose to participate, we'd see self-selection bias. Not all Internet users would choose to participate so the results may be skewed. There might also be measurement error. In a survey, for example, some of the responses may be unclear.

Sometimes the researcher adds bias. In a survey, a question may be worded in such a way that people respond in a different way than they would have if the question was not leading. Or the researcher may limit who can participate in the study. Iin a national survey about household income, if the researcher only calls homes at noon , this might not be representative of all people since many are at work during that time. Good researchers design their experiments to eliminate bias as much as possible.
