PART 1
TASK 1
a.
Expenditure (£) on Stand Mixers
Mean 224.00
Standard Error 6.58
Median 224.00
Mode 224.00
Standard Deviation 75.00
Sample Variance 5625
Kurtosis -0.49
Skewness -0.32
Range 301.00
Minimum 68.00
Maximum 369.00
Sum 29120
Count 130
Coefficient of Variation 33.5%
b.
With the help of the above descriptive statistics it is clear that the mean value evaluates
that the average number of people who are spending on the stand mixer is 224. On the other hand
is standard deviation outlines the dispersion of the data from the main value which is 75. This
implies that the deviation between mean value suggest that the data is highly dispersed.
