Description
SIMPLE TABLES (STRUCTURED DATA) Data: Raw facts. Information: Data made useful by rearranging/processing (Filtering, Sequencing, Calculating) E.g: Filtering & Calculating: Average Grade for sections, Count of males & females, Average GPA for majors Sequencing & Filtering: Alphabetical list by majors/ just Finance major Field: (Column) Characteristic or attribute of the entity. Record: (Row) Stores data on a specific occurrence of the entity; made up of fields. Table (entity): stores data on a single entity type; made up of of records Record layout: For every record is identical, same field in the same order Unique fields: cannot duplicate entries. Non-unique fields: Duplicates are permitted When you do searches, it is important to know if it is unique or non-unique Simple table (structured data) vs Excel table: Created from a simple table with the insert table command Excel’s rules for creating tables: • Field names (Header rows) should be descriptive, unique, no blank cells and must be formatted differently • Data records start in row immediately after field names, must be consistent, unique and on separate rows • No blank space at the beginning of the entry • Blank row above (except row 1) and below the last record; to the left (except column A) if the first field and right of the last field Excel’s rules for creating fields: • Use data that requires the least amount of maintenance (bdate instead of age) • Store the data in the smallest usable unit (last name & first name)  Greater flexibility • Store numeric data that you will not calculate with as text (ID, phone #)  Format before entering data Filtering data : W/in the same field  OR, AND can be done with numeric data (preset filters: between). Different Fields  AND (can’t use OR) Sequencing data Ascending: Oldest date, Smallest number, A-Z vs Descending order: Newest date, Largest number, Z-A Primary sort keys: Grouping by vs Secondary sort keys: w/in primary (if using A-Z/Z-A key  sequence Secondary first Subtotals: Sequence on the group first (sum, average, max, min, count). Can collapse/expand the outline. Cannot be inserted in an Excel Table. Don’t replace current total PIVOTTABLES AND PIVOT CHARTS Purpose: Make it easy to summarize and analyze large amounts of data. Easily rearrange the fields to look at the data from different perspectives. Can go on the same/separate worksheet Value fields: Text = Row labels. Numeric = Value area (Sum) (Can have multiple value fields). Text dragged in value area (Count). Report Filter fields: Allow filtering Ability: Adding/Removing fields; Rearranging fields; Sorting and filtering fields; Grouping items Refreshing PivotTable data: Change table data, doesn’t automatically update, has to refresh st Creating Pivot Charts: Build a pivot table and pivot chart. X-axis (category label) = 1 column Modifying PivotCharts: Can switch rows and columns. If modified, pivot table is also modified Slicers: Allow filtering by any field (w/in or outside a PivotTable). Can connect multiple PivotTable with 1 slicer LOGICAL FUNCTIONS IF Function (condition, true, false). Condition can be compound VLOOKUP Function - (What to look up (Cell), Lookup table, column #, True/blank (if approximate) or False (if exact). E.g: VLOOKUP (G4, \$E\$11:\$H\$15, 2, false). Have to be in ascending order if approximate match Conditional formatting Finding duplicates through Highlight Cells Rules: To look for error in uni
