Choose 5 of the variables and create a bar chart with the results for each variable - 5 bar charts Choose 5 different variables and create pie graphs for each of these 5 variables - 5 pie charts For the variable of age, create a "grouped" bar chart using the age groupings as follows. Count how many ages are in each of these groups and then create a bar chart for this data. Choose any 3 numeric variables and find the mean, median and standard deviation for each of these variables. Choose any 3 non-numeric variables and find the mode of each of these variables. Include a brief statement as to what the mode is telling you about that variable and the class response to it. Choose any 5 variables and find the simple probability of an event. For example, suppose we had a variable of car color and there were 15 white car owners, 10 blue car owners and 3 red car owners. Then the probability that a person from the class had a blue car would be P(blue car) = 10/28 = .357 Choose any 3 variables and compute "OR" probabilities. For example, if we had the car color example, you could have this as an example P (blue car OR red Car) = 10/28 + 3/28 = 13/28 = .464 8. Choose any 3 sets of 2 variables and compute "AND" probabilities. For these you must make sure that the variables are independent. So, for this one you could not use the 2 questions, have you traveled outside of the country and if so, how many countries have you visited. You could not use these 2 together, as they are not independent. For example, suppose in addition to the car color data we also had a variable for dog owners. Let's say we found 12 dog owners and 16 non dog owners. So an AND probability could be P (person has red car AND is a dog owner) = 3/28 middot 12/28 = .0459 Which of the variables gave you the most interesting results? Why
