This assignment requires a substantial amount of computer work and written comment. You may need to seek guidance from your tutor along the way. Do not leave things until too late!! The questions explain what is required and provide some information about the presentation of your answers. Follow the instructions carefully! Some Hints & Tips about the questions and presentation are given below. Make sure you read and follow these carefully. In particular you should take note of sections 1 and 2 from the Hints & Tips below regarding presentation of answers. Some Hints and Tips: Make sure the front page of your assignment includes both your name and your student number The questions in this assignment are numbered. Your answers should also be numbered. Please follow this numbering. Note that since the assignment may need to be scanned and then reproduced in black and white avoid the use of colour wherever possible. Make sure that all graphs are readable in black and white. Excel can have a tendency to insert coloured backgrounds, particularly on scatterplots, which completely hide the graphs and data points when converted to B and W! Remove such coloured backgrounds. Recall that just because data for a variable is numerical does not mean that it is quantitative! In all your tasks only include information that has been requested: for example, the summary table in part 4 should be one table including the average, the standard deviation and the number in each group. To examine the complaint raised in part 6 focus upon whether the increases were lower or not. Resist the temptation to talk about “fairness” and “gender bias” as we have no information about these aspects. To answer the question raised in part 7 we really need data giving % increases in salary for each year, and for each employee. This means going back and re-examining a large amount of data from many years – a very large task. Since we have not got this data, we will do something less. The horizontal axis is year of first employment. The trend line you have been asked for is linear. View Less >>
