2 Operators  What are the operators we discussed last time?  This time -- Conditional Operators:  IF  SUMIF  COUNTIF

3 IF in the real world... IF you get 8 hours of sleep THEN you’ll feel fresh in the morning ELSE you’ll feel tired in the morning IF you’re a Carolina fan on game day THEN you’ll wear Carolina blue ELSE you will wear whatever you feel like

4 IF in excel…  IF (logical_test, value_if_true, value_if_false)  Logical test: the thing we’re checking for true or false  Value_if_true: what should happen if our test was true?  Value_if_false: what should happen if our test was false?

5 Simple IF Example…  Is the number in the cell greater than seven?

6 More complicated IF example Let’s assign letter grades to the students! 90 - 100 – A 80 - 89 – B 70 - 79 – C 60 - 69 – D <60 – F

7 COUNTIF in the real world  How many brunettes are in class?

8 COUNTIF in excel…  COUNTIF(range, criteria)  range – a collection of cells that we’re checking against our criteria  range example: I2:I9  criteria some logical test for our range  Criteria example: “>=60”  criteria needs to be in quotes

9 COUNTIF example  How many courses is each student passing?  How many courses did at least one student pass?

10 SUMIF in excel  SUMIF (range, criteria, sum_range)  This function will add things up, depending on the criteria given.  range – a range of cells  ex. I2:I9  criteria – the criteria we’re checking against  sum_range – the range of cells to add up

11 SUMIF example  How much would it cost to buy one of every kind of vegetable?  How much would it cost to buy one of every kind of fruit?

12 On your own (or in groups)  Buy the grocery item if it is a fruit and if it costs less than $2.50.  Label the grocery items as inexpensive ( $2)  Sum up the even numbers from the list.  Hint: use ISEVEN(someNumber) & ISODD(someNumber)  Sum up the odd numbers from the list
