1. FILTERING DATA IN EXCEL
Filtering shows only those records that satisfy the stated criteria. (The remaining records will be hidden but not deleted.) You may use either the Simple or the Advanced filter features. We will restrict our attention to Simple, since it can be used for most common data- retrieval operations.
To filter the data using Simple, do either of the following:
1. Select any cell within the list and then choose Sort & Filter/Filter from the Editing group within the Ribbon’s Home tab.
2. Select any cell and then choose Filter from the Sort & Filter group within the Ribbon’s Data tab.

2. Example 8.4 Filtering a List in Excel
In this example, we will perform several filtering operations on the data within the list of states, originally created in Example 8.1. In particular, we will determine:
1. The 10 states having the highest population density.
2. Which state has its capital in Richmond.
3. Which states have areas exceeding 100,000 square miles.
4. Which states have populations between 10 and 20 million people.

3. Problem 8.4
Carry out the following filtering operations on the list containing the data given in Example 8.1. (a) Determine the five states having the smallest area. (b) Determine which state has its capital in Jefferson City. (c) Determine the total population of the three states having the largest area. (Hint: use AutoSum after the filtering operation.) (d) Determine the total area of the four states having the largest population. (e) Determine the average population density of the five states having the smallest population. (f) Determine which states have populations exceeding eight million people. (g) Determine which states have areas less than 60,000 square miles. (h) Determine which states have populations exceeding 16 million people or areas less than 70,000 square miles. (i) Determine which states have population densities between 65 and 200 persons per square mile. (j) Determine which states have state capitals whose names begin with either A or B. (k) Determine which states have populations between three and nine million people and areas between 60,000 and 80,000 square miles.

5. Problem 8.5
Enter Professor Boehring’s class roster, given in Prob. 8.2, into an Excel worksheet. Then carry out the following filtering operations: (a) Determine which students are industrial engineering (IE) majors. (b) Determine which students are majoring in either chemical engineering (ChE) or mechanical engineering (ME). (c) Determine the average scores of the civil engineering (CE) students. (d) Determine which students have final grades of C or better. (e) Determine which students have final scores less than 70. (f) Determine which electrical engineering (EE) students have final scores less than 70. (g) Determine which students have final scores between 70 and 90. (h) Determine which students are either industrial engineering majors or have final scores of at least 90.
