Tables, Radiativity Diagrams
Table1
A table of this would be computer as follows
X:1,2,3,4
FX:4,6,8,10
F(X-Xbar):10,8,6,4

Table2

A table like this would be computed as follows
Particulars: maintenance,salaries &wages, Purchase of
Drugs, total
Amount: 2500,1000,2000,5500
Logarithm Table
Tabulate
No: 92.63, Log: 1.9667
No: 2.914, Log: 0.4645
2.4312
Antilog = 269.9
Therefore 92.63 * 2.914=2.4312
