Lab Statistics Week 2 Name: John Matias DSI:03156412__ Math221 Statistical Concepts: Using MINITAB Graphics Shapes of Distributions Descriptive Statistics Empirical Rule Data in MINITAB MINITAB is a powerful, yet user-friendly, data analysis software package. You can launch MINITAB by finding the icon and double clicking on it. After a moment you will see two windows, the Session Window in the top half of the screen and the Worksheet or Data Window in the bottom half. Data have already been formatted and entered into a MINITAB worksheet. Go to the eCollege Doc sharing site to download this data file. The names of each variable from the survey are in the first row of the Worksheet. This row has a background color of gray to identify it as the variable names. All other rows of the MINITAB Worksheet represent a certain students answers to the survey questions. Therefore, the rows are called observations and the columns are called variables. Included with this lab, you will find a code sheet that identifies the correspondence between the variable names and the survey questions. Complete the answers below and paste the answers from MiniTab below each question. Type your answers to the questions where noted. Therefore, your response to the lab will be this ONE document submitted to the dropbox. Code Sheet Variable Name Drive State Temp Rank Height Shoe Question Question 1 How long does it take you to drive to the school on average (to the nearest minute)? Question 2 What state/country were you born? Question 3 What is the temperature outside right now? Question 4 Rank all of the courses you are currently taking. The class you look most forward to taking will be ranked one, next two, and so on. What is the rank assigned to this class? Question 5 What is your height to the nearest inch? Question 6 What is your shoe size? Sleep Gender Race Car TV Money Coin Die1 Die2 Die3 Die4 Die5 Die6 Die7 Die8 Die9 Die10 Question 7 How many hours did you sleep last night? Question 8 What is your gender? Question 9 What is your race? Question 10 What color of car do you drive? Question 11 How long (on average) do you spend a day watching TV? Question 12 How much money do you have with you right now? Question 13 Flip a coin 10 times. How many times did you get tails? Question 14 Roll a six-sided die 10 times and record the results. Creating Graphs 1. Create a Pie Chart for the variable Car Pull up Graph > Pie Chart and click in the categories variables box so that the list of variables will show up on the left. Now double click on the variable name Car in the box at the left of the window. Include a title by clicking on the Labels button and typing it in the correct text area (put your name in as the title) and click OK. Click OK again to create graph. Click on the graph and use Ctrl+C to copy and come back here, click below this question and use Ctrl+V to paste it in this Word document.

Enter 10 for the Increment: and click OK. The leaves of the stem-leaf plot will be the ones digits of the values in the Money variable. Note: the first column of the stem-leaf plot that you create is the count. The row with the count in parentheses includes the median. The counts below the median cumulate from the bottom of the plot.

Check By variable: and enter Gender into this text box. Click OK. Type the mean and the standard deviation for both males and females in the space below this question. Females Mean 67.273 Standard deviation 2.533 Males 69.78 4.21 Select File > Save Worksheet As to save the data set. You must either keep a copy of this data or download it again off the web site for future labs. Short Answer Writing Assignment All answers should be complete sentences. 5. What is the most common color of car for students who participated in this survey? Explain how you arrived at your answer. The most common color is silver and Blue. The way I arrived at this answer is I grouped together the colors to count how many. 6. What is seen in the histogram created for the heights of students in this class (include the shape)? Explain your answer. Most of the data is on the right. Therefore it is Left-skewed. 7. What is seen in the stem and leaf plot for the money variable (include the shape)? Explain your answer. Most of the data is on the left. Therefore it is Right-skewed. 8. Compare the mean for the heights of males and the mean for the heights of females in these data. Compare the values and explain what can be concluded based on the numbers. The females are shorter than males on average. 9. Compare the standard deviation for the heights of males and the standard deviation for the heights of females in the class. Compare the values and explain what can be concluded based on the numbers. The females heights are more disperse than the male heights. Therefore, there are more females taller and shorter than the average, than there are males. 10. Using the empirical rule, 95% of female heights should be between what two values? Either show work or explain how your answer was calculated. Therefore 95% of the female heights fall within 62.207 and 72.339 11. Using the empirical rule, 68% of male heights should be between what two values? Either show work or explain how your answer was calculated. Therefore, 68% of the males heights fall within 65.57 and 73.99
