“Instructions for the computing assignment worth 20% of your final grade Overview Materials that must be used in the assignment, these are provided on moodle *A pair of datasets for country 1 and country 2. Looking at the datasets you will notice that each student has been given a sample, students must use their own sample. *An automatic dataset summarizer. *Instructions for checking that you have properly found your sample, students must use their sample. Students must submit a word file AND an excel file to moodle *The word file needs to be submitted to the Turnitin link, the word file needs a cover page and the answers to 9 questions given in full detail later in this document (pages 2 to 7) a vital part of answering the question is using the dataset and the dataset summarizer. *The excel file needs to be submitted to the assignment dropbox, the excel file should have the students dataset for country 1 and summaries NOT made by the automatic dataset summarizer students need to summarize the dataset using PivotTables and the scatterplot. Instructions for submitting the excel file are given on page 8“ “Instructions for the Major part of assignment , the word file worth 18% of your final grade you submit to Turnitin. Use the following as the cover page for the word file “Title: semester 1, 2020 BUS105 computing assignment” “Name:” “Student number:” “Sample: ” “(students must use the dataset provided each student has been allocated their own sample)” Overview You need to submit a word file with the answers to 9 questions the first 8 are about the dataset the last question is a paraphrasing task (refer to pages 3 to 6) You will use your dataset and the automatic dataset summarizer to get the descriptive statistics that are used questions 1 to 5 and the inferential statistics that are used in question 6 to 8. to check you have correctly obtained your dataset check both p-values are correct when you investigate both categorical variables (question 6) The word count can be less than 1500 words if you are giving answers that demonstrate you have understood the material. Summary of the dataset (question 1 to 8 given on pages 3 to 6 are about the dataset) Suppose market research company XYZ did a survey in two different countries. The survey was designed to gather basic information about some customers and their opinion about TV model XYZ The survey questions were “What is your Income?” “What is your gender?” “How much are you willing to spend on a TV?” “Would you buy TV model XYZ?” So there are two datasets, one for each country One dataset is the survey answers country 1 One dataset is the survey answers country 2 students MUST use the datasets they are given, They CANNOT use datasets they make themselves or take from other sources. Each of the datasets consists of the following variables, income? : a quantitative variable Gender?: a categorical variable Amount you would spend? : A quantitative variable, the amount they would spend on a TV Would you buy?: A categorical variable, would they buy TV model XYZ paste the following cover page and the answers to questions 1 to 9 below into a word document “Title: semester 1, 2020 BUS105 computing assignment” “Name:” “Student number:” “Sample: ” “(students must use the dataset provided each student has been allocated their own sample)” Question 1 a) Just using the information for Country 1 i) Paste in descriptive sample statistics that let you investigate the relationship between the variables “Gender?” and “Would you buy?” using the sample ii) Use the output in part (i) to describe the relationship between the two variables, your discussion must use one of the following sample statistics (choose one) Difference between sample means - Difference between sample proportions - correlation coefficient r b) Just using the information for Country 2 i) Paste in descriptive sample statistics that let you investigate the claim there is a relationship between the variables “Gender?” and “Would you buy?” ii) Use the output in part (i) to describe the relationship between the two variables, your discussion must use one of the following sample statistics (chose one) Difference between sample means - Difference between sample proportions - correlation coefficient r c) Compare the results in parts (a) and (b) Question 2 a) Just using the information for country 1 i) Paste in descriptive sample statistics that let you investigate the relationship between the variables “Would you buy?” and “amount you would spend?” using the sample ii) Use the output in part (i) to describe the relationship between the two variables, your discussion must use one of the following sample statistics (chose one) Difference between sample means - Difference between sample proportions - correlation coefficient r b) Just using the information for Country 2 i) Paste in descriptive sample statistics that let you investigate the claim there is a relationship between the variables “would you buy?” and “amount you would spend?” ii) Use the output in part (i) to describe the relationship between the two variables, your discussion must use one of the following sample statistics Difference between sample means - Difference between sample proportions - correlation coefficient r c) Compare the results in parts (a) and (b) Question 3 a) Just using the information for Country 1 i) Paste in descriptive sample statistics and a graph that let you investigate the relationship between the variables “Income?” and “Amount you would spend?” using the sample ii) Use the output in part (i) to describe the relationship between the two variables, your discussion must use one of the following sample statistics Difference between sample means - Difference between sample proportions - correlation coefficient r b) Just using the information for Country 2 i) Paste in descriptive sample statistics and a graph that let you investigate the claim there is a relationship between the variables “Income?” and “Amount you would spend?” using the sample ii) Use the output in part (i) to describe the relationship between the two variables, your discussion must use one of the following sample statistics Difference between sample means - Difference between sample proportions - correlation coefficient r c) Compare the results in parts (a) and (b) Question 4 a) Considering all people in the country 1 dataset i) What is sample size n ii) What is the sample proportion of people that would buy the model XYZ TV iii) Use the answers in part (i) and (ii) to find the zscore of the sample proportion if you assume the population proportion p=0.5 b) Considering all people in the country 2 dataset i) What is sample size n ii) What is the sample proportion of people that would buy the model XYZ TV iii) Use the answers to parts (i) and (ii) to find zscore of the sample proportion if you assume the population proportion p=0.5 Question 5 Just using the country 1 data set, more specifically the “variables income” and “would they buy” of the country 1 dataset a) Just considering the people that would buy the TV i) What is sample size, sample mean and sample standard deviation of income Hint: this is easy just the dataset summarizer ii) find a 95% confidence interval for income b) Just considering the people would not buy the TV i) What is sample size, sample mean and sample standard deviation of income Hint: this is easy just the dataset summarizer ii) find a 95% confidence interval for income Question 6 a) Just using the information for country 1 i) Paste in inferential statistics that measure evidence for the claim there is a relationship between the variables “Gender?” and “Would you buy?” if you consider the whole population ii) Make suitable comments about the output in part (i) b) Just using the information for country 2 i) Paste in inferential statistics that measure evidence for the claim there is a relationship between the variables “Gender?” and “Would you buy?” if you consider the whole population ii) Make suitable comments about the output in part (i) c) Compare the results in parts (a) and (b) Question 7 a) Just using the information for country 1 i) Paste in computer output that measure evidence for the claim there is a relationship between the variables “would you buy?” and “amount you would spend?” if you consider the whole population Hint: inferential statistics measure evidence for a claim. ii) Make suitable comments about the output in part (i) b) Just using the information for country 2 i) Paste in computer output that measures evidence for the claim there is a relationship between the variables “would you buy?” and “amount you would spend?” if you consider the whole population ii) Make suitable comments about the output in part (i) c) Compare the results in parts (a) and (b) Question 8 a) Just using the information for country 1 i) Paste in computer output that measures evidence for the claim there is a relationship between the variables “Income?” and “amount you would spend?” if you consider the whole population Hint: inferential statistics measure evidence for a claim. ii) Make suitable comments about the output in part (i) b) Just using the information for country 2 i) Paste in computer output that measures evidence for the claim there is a relationship between the variables “Income?” and “amount you would spend?” if you consider the whole population ii) Make suitable comments about the output in part (i) c) Compare the results in parts (a) and (b) Question 9 You need to pick ONE of the following options for question 9, Your answer should be about 300 words long OPTION 1 Give a brief summary of at least on the major ideas in the following power point available from https://app.box.com/s/0eddpa7wut2kdae4nmkynrz0fgfdcrbg Do not cut and paste text and use a computer to randomly change the words OPTON 2 Briefly discuss the main message in the following sample report available from https://app.box.com/s/ael5pciel84wnveu3z4bd74ro0v2djgn (you need to click download, logging in will not work) and discuss how it is communicated.
