A project is shown below. The project consists of a set of data with three independent questions. The first question should ask you to create a histogram or bar graph for some variable categorized by age and split for men and women. This extends the idea of bar graphs because you will use the ages as the classes, but the height of your bars will be the average (mean) of the variable within each age bracket for men and for women. The most common error for this graph is having a bar for every single data point, rather than a single bar for men and a single bar for women within each age group. The second question will ask for a pie chart for some variable. The most common mistake for the second question is that people get stuck on splitting the data into men and women. For this question, when it does not ask you to separate men and women, it asks for a single pie chart for the frequency of the variable without regard to gender. The last question asks for basic central tendency and dispersion. For this, the only mistake some people seem to make is to possibly miss one of the measures of central tendency or dispersion. Or, occasionally someone will break the data down into categories from the prior
Statistics Individual Project Using Data Set 1
Create a bar graph using two different colors to represent the male and female categories. Use age to categorize and graph the average height.
Create a Pie chart to represent the age bracket of participants.
Compare males and females Cholesterol levels. Support your results by including all measures of central tendencies and measures of dispersion that we have covered in this course.
