PART 1
TASK 1: Ungrouped Descriptive Statistics
(a) On standing processors, the data displays the average mean and standard deviation from
the operations list.
Expenditure (£) on Stand
Mixers
Mean 224.00
Standard Error 6.58
Median 224.00
Mode 224.00
Standard Deviation 75.00
Sample Variance 5625.09
Kurtosis -0.49
Skewness -0.32
Range 301.00
Minimum 68.00
Maximum 369.00
Sum
29120.0
0
Count 130.00
Coefficient of
Variation 33.5%
(b) The unknown mean and standard deviation for standing processors expenditures are £224
and £75, correspondingly. Because the average is larger than the normal variation in this
data, we could deduce that the data are clustered around the average. The mean, median,
and mode numbers are all the identical, resulting in a regular dispersion of expenditures.
TASK 2: Grouped Descriptive Statistics
(a) Table 1 , 2 and 3 are as follows:
Expenditure (£) Frequency
Frequency
(%)
Under 100 15 11.54
100 and under 200 34 37.69
200 and under 300 64 86.92
300 and over 17 100
