Some general feedback for BUS708 Assessment 1

• Some students gave a very short description about dataset 1 and failed to explain what it is about and/or the source of the dataset.
• Many students did not list the categorical and quantitative variables of Dataset 1.
• The main reason that dataset 2 might be biased is not because it does not cover the whole population. Dataset 2 is most likely biased because it might not be a representative of the population (e.g. only from KOI or other institutions, volunteer sampling, convenience sampling, etc.). Some students said that their sample is random but did not explain how they made sure it’s random.
• Many students wrote reasonable comments, but many failed to answer the research question. You should have a concluding statement that answer the research question.
• Many graphs are still missing a title and axis labels.

Hints for Assignment 2

• Make sure you mention the objective of the report or what is the report about, including short description of the datasets. This can be one paragraph in Section 1.
• Write a proper literature review, including in text citation. Some example can be found in http://anglia.libguides.com/ld.php?content_id=14268350. Paraphrase the article, don’t just copy paste its content. This can be another paragraph in Section 1.
• Make sure you explicitly answer the research question in each section.
• Check that your graphs are complete (title, labels or legends).
• Check and re-check marking criteria to make sure you address all the criteria.

This BUS708 Assessment 2 Sections and the following sections are just examples, they may have different dataset and/or different research questions.

data presentation

Please write something here to introduce what you will present.

Then copy paste your results from Excel (without the comments, as you will write new comments). Below is just some examples, your results might be different.

Inferential statistics

The following is just an example. Please write something for an introduction.

Sample size (n) = 10000
Sample proportion ( ) = 0.5043
Standard Error (SE) =  = ….
Use information to test a hypotheses test for proportion.

….. <write your conclusion here>

data presentation

Please write something here to introduce what you will present.

Inferential statistics

Please write something here to introduce what you will perform

Sample size (n) = 117
Sample mean (Xbar) = 898.51
Sample standard deviation (s) = 413.99

Find 95% confidence interval.

From Statkey, Theoretical Distributions: t, with df = n-1 = 229

<Write your conclusion here>

This is a model answer for section 6

data presentation

Please write something here to introduce what you will present.

Inferential statistics

Please write something here to introduce what you will perform.

Step 1:

H0: All means are equal  à change to be more specific
H1: Not all means are qual à change this

Step 2:

ANOVA Table

So the test statistic = 74.074

Step 3:

p-value = 0.000 (from Statkey with numerator df =…

Step 4

Reject H0

There is strong evidence of a difference in weekly rent among ….

This is the model answer for section 5

data presentation

You need to perform regression analysis and paste in some output in here. You can either use Excel (Data > Data Analysis > Regression) or Statkey. Note that most likely you will need to make a new scatter plot as the order of X and Y may be different.

Please write something here to introduce what you will present.

Inferential statistics

Please refer to the marking criteria to see what inferences you need to make. Also make sure you make a conclusion that answer the research question.

Corr coef = …  so there is weak/moderate/high positive/negative correlation between …

Coef determination = ….  

p-value = …  dfd

This is the model answer for section 4

data presentation

Please write something here to introduce what you will present.

Inferential statistics

Please write something here to introduce what you will perform.

H0: fdfd
H1: dfdfd

Test-statistic = 37.333 (using STatkey)

p-value = 0.000050  (From Statkey, df = (3-1)(6-1) = 10)

<write conclusion here>

To perform Chi-square test in Statkey:

1. Go to Statkey website http://www.lock5stat.com/StatKey
2. Choose “More Advanced Randomization Tests:  Test for Association”

• Click Edit Data then copy and paste your Dataset 2

Make sure you tick “Raw Data”

• Click on the Summary

• To find p-value, go to Statkey main page, and select: Theoretical Distributions:  
• Enter df = (#rows -1)(#cols – 1)

Section 7: Conclusion & Recommendation
