Glade Manual – Chapter 3
1
e.g. In exercise 2: Kasch Pulse Recovery Study- We want to identify the “Fitness Rating” for a list of people
based on their “Pulse Rate” readings:
• Nested “IF” function:
The IF function template require three arguments – a logical test, the value to return if the test is true, and the value to return if the test is false. In this example there is not just one logical test – there are 5!

• Nested “IF” function:
The logical implementation would be:if(Less than 80, “Excellent”,
if(80 to <90, “Good”,if(90 to <105, “Average”,
if(105 to <115, “Fair”, “Poor”))))
0 9080 105 115
Fair PoorAverageExcellent Good

• “LOOKUP” function: - Instead of using “Nested-if” function for the above scenario, the
“LOOKUP” function can be used to simplify the implementation
- In Excel: “=LOOKUP(lookup_value, lookup_vector, result_vector)”- There are 3 items need to be referred to.

• “LOOKUP” function:
- In exercise 5, you are asked to determine the “Fitness Rating” of a list of people depends on their gender.
The basic idea is to say:If (subject is male, lookup the table for males, lookup the table for females)

This exercise also introduces the idea of a compound logical test involving the use of the “AND” and “OR” functions
In this exercise:
• Exercise 3 (Sales Discount Model):
If ( it’s a women’s clothing item AND it’s not selling well), discount by 25% , otherwise no discount
The basic idea is to say:
IF (it’s a women’s clothing item AND it’s not selling well)
Value_if_true: discount by 25%Value_if_false: no discount
Logical 1 Logical 2

• Exercise 3 (Sales Discount Model):
IF (it’s a women’s clothing item AND it’s not selling well)
Value_if_true: discount by 25%Value_if_false: no discount
Note: “women’s clothing” is labeled as “CW” in the “Product Code”
Logical 1: are the first two characters of product code = CW?Logical 2: “not selling well” means “Stock_Quantity > 15*Average_Daily_Sales”
Logical 1 Logical 2

Exercise 1 (Sales Person Bonus Model) [formula view]Use “IF” function to determine the “Bonus” of a salesperson
Exercise 3 (Sales Discount Model) [formula view]Use “AND” and “LEFT” (i.e. from the Text group of functions) functions in a “IF” logical statement to determine which “clothing – women’s” items need to give a discount of 25%
Exercise 5 (Kasch Pulse Recovery Study Again) [formula view]Use “IF” and “LOOKUP” functions to determine the “Fitness Rating” for both men and women
