Conclusions

Each statement/question (1 – 9) will be marked against the following scheme, although there is some variation between them depending on the perceived complexity of the analysis required.

In addition there are 8 marks in total for :

Title,	A suitable title
Introduction :	A description and philosophy of the data housing ads (rough maximum 300 words)
Data collection and coding	A description and presentation of your coding scheme. If a third party reads this section they should be able to recreate your data set from the raw, printed data (rough maximum 300 words).

In total the assignment is marked out of 100.

Remember that you should be presenting appropriate tables and extracting the salient features in a clear and logical manner and in a way which allows your conclusions to be justified. You will have covered all the statistical techniques required during the classes, either this year or last year.

When the results are given this should include the appropriate statistical output, suitably edited to remove extraneous information. Marks will be lost for the inclusion of over populated tables.

Any comments derived from the analysis should be supported by the relevant statistics.

Arrange the analysis of each question in a logical manner including the question being answered. As each statistical table is presented it should be followed by comments on that table. It is inappropriate to present several tables one after the other and then comments about all of them at the end, requiring the reader to keep looking backwards to search out the related information.

Set information out clearly and present your arguments in a logical manner. Keep it simple.

You do not need to include a printed copy of the original data or a printed copy of your SPSS data file in the report.

Remember to number each page of your report in case it gets dropped, then we can put it back together in the correct order. Your assignment must be stapled and have a pink cover slip (provided) attached.

		What is the average number of bedrooms for the houses?
	b)	Produce a histogram of the number of bedrooms . Describe the shape of the distribution. Are the data normally distributed? Support your answer with appropriate statistics. Apart from normality, why might you be concerned about analysing the data using parametric tests?

(2)

Is there an association between the specific mention, or not, of a conservatory and the house type (detached, semi detached and terraced)? If so describe what this relationship is. Justify your answer by the use of appropriate statistical tests.
.

(3)

At a meeting an estate agent says that properties that have or have not an en-suite are always present in the ads in the ratio 2 : 3 . Can this statement be supported? Justify your answer by the use of appropriate statistical tests.

(4)

Is there any difference in the mean number of additional features between those that specify a conservatory and those that do not? Justify your answer by the use of appropriate statistical tests.

(6)

At a meeting of estate agents one agent says he observed that the number of rooms in a house fall into one of three groups, and that there is a relationship between the group and type of house (detached, semi detached and terraced). Can this latter statement be supported? Justify your answer by the use of appropriate statistical tests.
Group A 0 to 5 rooms
Group B 6 to 9 rooms
Group C 9 or more rooms

(7)

As the number of additional features in each property increases so does the number of words in the individual advertisements . Can this statement be supported? Justify your answer by the use of appropriate statistical tests.

(8)

Divide the price of a house by the number of rooms (excluding bedrooms) . Give the mean of this ratio and the mean for the number of rooms (excluding bedrooms) and then draw a suitable graph to show the relationship between this ratio and the number of words in the ad.
Relate this to the correlation between the number of words in the ad and the ratio.
The graph should also show visually the different areas the properties are in. Are there any discernable patterns to the data?

(9)

Generate a predictive equation for the number of additional features using price as the independent variable.
How many additional features would a property valued at £200,000 be estimated at?
