University College London Descriptive Statistical and Graphical Summaries

ALL STATISTICAL ANALYSIS SHOULD BE UNDERTAKEN USING SPSS.

A manufacturer of household cleaning products is interested in increasing customer awareness of its new environmentally sustainable range. The company recruits a sample of 44 customers. 22 of these customers were sent a publication which included advertising materials about the new cleaning products. Two weeks after this, all 44 customers were asked to complete a survey about their awareness of the new products. The company wants to know if the advertising campaign is worth administering to all of its customers. In other words, are the awareness scores of those who were exposed to the advertising materials significantly higher than those of the group that was not exposed.

You have been provided with data comprising the awareness levels of each customer, broken down according to whether or not they had been exposed to the advertising campaign.

Provide descriptive statistical and graphical summaries of the two sets of data. Suggested word count 100-200 words

Analyse the data using an independent samples t-test. Suggested word count 300-400 words

Use a suitable non parametric test to investigate the impact of the advertising campaign on awareness. Suggested word count 100-200 words

Compare the results of each test and state, with an explanation, which test is most appropriate. Suggested word count 300-400 words

The marking criteria focus on your technical ability and your ability to express the results clearly and concisely in technical and non-technical terms.
