BBS300- Use Appropriate Graphical Displays and Measures of Centrality and Dispersion – Empirical Research Methods for Business Assignment, Singapore

Assignment Details:

In this assignment, we will examine the“Car Manufacturers” dataset. Before beginning the assignment read through the descriptions of the variables in the data set. Each variable in the dataset is described in the ‘label’ field of the SPSS file.

Question1: Use appropriate graphical displays and measures of centrality and dispersion to summarise the following five variables. For graphical displays for numeric data, be sure to comment on not only the shape of the distribution but also compliance with a normal distribution. Be sure to include relevant SPSS output (graphs, tables) to support your answers.
(a) Seconds to reach to speed 60 from 0.
(b) Weight in 100 lb.
(c) Horse power.
(d) Gallons per 100 miles.
(e) Cylinders.

Question 2: Again consider the variable ‘Gallons per 100 miles’, and ‘Seconds to reach to speed 60 from 0’. It is of interest to visualize the relationship between the two variables. You must report the shape of the relationship.

Question 3: Consider the variables ‘Horse power’ and ‘Seconds to reach 60 from 0”. It is of interest to identify the outliers in those two variables. You must generate two graphs that indicate the cases of the outliers and then report the values of each outlier case.
