This assignment will allow you to apply the information you have learned so far in this course. This assignment must be typed and should be a formal document. Handwritten documents will not be accepted. If needed, graphs may be drawn by hand, but they will need to be scanned and loaded into the document in the spot they are required. Documents may be typed in WORD and may be submitted as a word document. All other documents must be scanned and changed to a pdf file. The projects are the tests for this course and the same time and attention should be paid to the projuect just like you would if you were preparing for a test.
ASSIGNMENT DETAILS: Do not copy this assignment and fill it in. Your project should follow this format and parts should be labled the the guidlines and directions should not be included in your project.
For this assignment you will need to pick a population that you can ask one quantitative question and one qualitative question. For example you could use a population of dog owners. You could ask “What breed is your dog” – qualitative and “How old is your dog” – quantitative. You will ask both questions to 20 people and gather 20 pieces of each type of data. For the purpose of this assignment, you need your quantitative data to be whole numbers so avoid things that will give decimals as answers. If your answers do have decimals, round to the nearest whole number. Some examples of what you could do are: Ask 20 dog owners, “What breed is your dog” – qualitative and “How old is your dog” – quantitative, record the weight of 20 NFL football players and the position they play (this can be done on the internet but you must make your data is random – don’t just use your favorite team), or record the price of 20 pairs of shoes and the type of shoe (you may look at in an online catalog or in a store you go to but keep it random – more than one site or more than one store). These are just examples and you should come up with a new example of your own. Be original and pick something that is of interest to you. This is your chance to make this coures relevant to you. This should not be a convenience sample. You can vary the data by not just picking the first 20. Depending on the size of your population, pick every third or fourth item. Also try different places to obtain your sample. The requirements are:
You must have 20 pieces of data for each question.
The qualitative question should have at least 4 unique categories. (for example if you were looking at breeds of dogs you could have beagles, poodles, golden retrievers and mixed breeds).
The quantitative values should be varied. In other words, if you are doing ages and everyone is between 18 and 20, this would not be a good example. You will want a range (highest value – lowest value) of at least 10 and preferably more.
Once you have your data, complete the following: Note: Graphs may be drawn with technology or by hand, but they should show all the important parts as stated in the videos and homework assignments and they should not contain extra information unless you explain what that information is. If you are using technology, the graphs need to be scanned and placed in the document in the correct location. If you are drawing your graphs you need to scan the graphs and place them in the correct spot. Graphs may not appear on a separate sheet.
Once you have the sample, you will need to do the following. Label each part on your docuent.
Part 1: Write one good paragraoh about your data Explain what your data stands for, why you chose this example, and how you obtained a random sample. (4 points)
Part 2: Construct a frequency table for your 2 sets of data. The quantitative table should have 4 classes. The number of classes in your qualitative table will vary depending on how many unique responses you got. Both tables should contain the classes, the frequencies and the relative frequencies. (6 points)
Part 3: Use your frequency tables to construct the following graphs. Be sure to include all required parts and remove (or explain) any extra information. These graphs should follow the standards shown in the videos. : (8 points)
Qualitative Data : Either a pie chart, a bar graph or a pareto graph (chose one).
Quantitative Data: Either a histogram or a frequency polygon (chose one).
Part 4: Use your quantitative data (do not use the frequency table) to find the following values. These values should be calculated with your calculator. They should not be calculated by hand. Round all answers to 3 decimal places. (14 points)
1. Mean
2. Median
3. Mode
4. Standard Deviation
5. Variance
6. First Quartile
7. Third Quartile
Part 5: Calculate the Interquartile range for your quantitative data and use it to determine if you have any outliers. If you do, what are they. Show calculations that justify your answers. (4 points)
Part 6: Construct a Box and Whisker plot for your quantitative data. (4 points)
Part 7: Find the mode for your qualitative data. (2 points)
Part 8: Using your answers from the previous parts answer the following questions. Each answer should be one or more sentences and the questions should be completely answered. (4 points)
Does the quantiative distribution seem to be symmetric, skewed left or skewed right? Use your measures of central tendency to explain why.
Intepret the value you got for the median of the quantitative data. Do not use words like center, middle or other words like that.
Interpret the mode of the qualitative data.
Which measure of central tendency (mean, median or mode) seems to be the best representation of your data and why.
