Homework 1 (non-Excel portion)
Fall 2023
Must be uploaded into Canvas by 11:55 pm on Friday, September 1, 2023.
Upon submitting this homework, I affirm that I have not given or received unauthorized aid
on this homework, and I completed this work honestly and according to the instructor’s guidelines.
Answers may be typed or handwritten.
Homeworks are graded on completion, not accuracy. Work must be shown on the homework to receive full credit. Credit for completion will not
be awarded if adequate effort has not been shown. Each homework is worth 2.5 points. So, for example, if a student gets a score of 2.5, it means that they did all the work, it does not
mean the answers are all correct
.
In order to promote professional development of students in learning the importance of appearance and presentation of submitted work, 0.1 point will be deducted from homework scores for each the following conditions that are not met (students could lose a total of 0.2 points for not meeting these conditions):
Questions numbered and done in order (all work and answers for each question in one place)
Increased space between each question if the answers are included on the posted homework assignment
If you take any definitions/concepts directly from the packet, please cite the page number in the packet
.
YOU MUST SHOW WORK TO GET CREDIT.
1.
According to the syllabus, explain in your own words
how homeworks are graded.
The successful completion of homework is graded, not correctness. If sufficient effort has not been made, credit for completion will not be given. Each assignment is worth 2.5 points; if a student receives that many points, they have completed all the required work but not necessarily all the questions correctly. After each student has turned in their homework, the answer keys will be published to Canvas. It is the student's obligation to check their assignment for faults by comparing it to the answer key.
2.
According to the “Academic Integrity” section of the syllabus, explain in your own words what happens when a student has
a first offense of academic integrity.
The student will not receive any credit for the assignment or exam.
a second offense of academic integrity.
The professor will, at the very least, report to the associate dean and the academic integrity committee that the infraction result in zero credits and a complete 2 letter grade deduction from the final course mark.
3.
According to the syllabus, explain in your own words what University Policy G:9 says.
According to university regulation G:9, if a student is informed that they are suspected of breaking the rules of academic integrity, they are not permitted to quit the course while the issue is being investigated. The student may not withdraw from the course whenever they choose if they are found guilty of the infraction. Unless the dean is considering a "trauma drop" and determines it is necessary.
4.
According to the “Homework Assignments” section of the syllabus, explain in your own words what students are allowed to do and what they aren’t allowed to do regarding working with others when completing homework assignments.
To better comprehend concepts and methods for solving problems, students are encouraged to collaborate with one another on their homework projects. All students must, however, complete their own work in the end by responding to inquiries and tackling issues in their own words and ways. Once a pupil begins to write, type, or create computer output, it must be entirely their own work and not someone else's.
(Questions 1-4 can be completed after the Introductory Lecture.)
5.
Name the five uses of models that were discussed in class and listed on p. 12 of the course packet. You must list all five to get credit. Number your answers so the graders can see that five are listed.
1. Making better decisions, 2. Communication, 3. Understanding concepts, 4. Identifying relationships and 5. Developing new models
6.
What are the two factors that are important in determining the appropriate statistical concept or technique for a given situation that were listed on p. 12 of the course packet? Both must be given in order to get credit. Number your answers.
1. Purpose or specific objective and 2. Type of data
7.
Which of the factors listed in Question 6 above should you work on first and why? You must list the factor and tell why in order to get any credit. Number your answers (#1 for the factor and #2 for why).
Purpose or specific objective as it will improve the chances of collecting useful data and not just random data which wouldn’t be of any help.
8.
What is the difference between nominal and ordinal data. Give an example of each. Use #1 through #4 for your answers (definition of nominal, example, definition of ordinal, example).
Nominal data: qualitative data units are placed in classes and have no natural ordering; ex: PSU ID number and car color. Ordinal data: qualitative data is ranked into some natural ordering; ex: hotel ratings and student class standing.
9.
What is the difference between interval scale data and ratio scale data. Give an example of each. Use #1 through #4 for your answers (definition of interval scale, example, definition of ratio scale, example).
Interval scale: no defined zero value and ratio is not meaningful; ex: temperature and dress sizes.
Ratio scale: defined zero value and ratio is meaningful; ex: prices and distances.
(Questions 5-9 can be completed after Lecture 1.)
10.
Tell which kind of data is used for bar charts and which kind of data is used for histograms? Number your answers.
1. Quantitative data for histograms and 2. qualitative data for bar charts.
11.
How are frequency histograms and relative frequency histograms similar and how are they different? Number your answers (#1 for similarity and #2 for difference).
#1 Both are representatives of quantitative data sets. #2 Frequency histograms have numbers on the y-axis whereas relative frequency histograms have percentages.
12.
Draw or type a stem and leaf diagram (do not use computer software) for the following data set:
91, 21, 7, 46, 29, 4, 22, 62, 4, 35, 19, 11, 21, 25, 13, 23, 12, 22, 13, 22, 31
Is this distribution symmetric, skewed right (positive), or skewed left (negative)?
(Questions 10-12 can be completed after Lecture 2.)
13.
Interpret the following: The 65
th
percentile of home prices in Champaign is $227,000.00.
This means that 65% of home prices in Champaign are equal or lower than $227,000 .
14.
For the following data set, find the mean, median, and mode(s): 8, 10, 16, 12, 10, 10, 11. The units are liters. Include the units in your answers if these are absolute measures. [Reminder that work must be shown on all math problems. Number answers with no work shown will not get credit; therefore, work must be shown for both mean and median (sorted data set) in order to get any credit.]
(Questions 13-14 can be completed after Lecture 3.)
