Study Notes

Data Analysis

Data analysis in Excel is the process of using Microsoft Excel to perform tasks related to analyzing and manipulating data.
Excel offers a wide range of tools for tasks such as data cleaning, summarization, visualization, and basic statistical analysis.

Sorting and Filtering

Sorting organizes data alphabetically, numerically, or by date and time.
Sorting can be done on one column, multiple columns, a custom list, or by color.
Filtering displays relevant data by eliminating irrelevant entries temporarily.
Filtering can be applied to one column, multiple columns, text, numbers, dates, and with advanced filters.

Data Validation

Data validation helps to ensure that data is accurate and consistent by setting rules for what data can be entered into a cell.
It can be used to create drop-down lists, to restrict data entry to certain values, or to prevent data from being entered in an incorrect format.
Data validation features include:
- Creating drop-down lists using data from a range of cells, a table, or a list.
- Allowing users to add or remove items from the list.
- Creating dynamic drop-down lists that change based on the value selected in another cell.
- Creating dependent drop-down lists where the values in the second list depend on the value selected in the first list.

Conditional Formatting

Conditional formatting helps visualize data to make worksheets easier to understand by applying different formats (e.g., colors, fonts, icons) to cells based on their values.
Predefined styles, or presets, can be used for quick conditional formatting.
It can be removed to revert cells to their original format.

What-if Analysis

What-if analysis allows users to try out different values, or scenarios, for formulas to see how changes in input values affect the output.
The Scenario Manager helps create and manage these scenarios.

Goal Seek

Goal Seek finds the input value that produces a desired formula result.
It can be used to determine how to achieve a specific target.

Solver

Solver is a tool used in Excel to perform "what-if" analysis by changing multiple variables to find an optimal solution for an objective, such as maximizing profit or minimizing cost.
It can be used for optimization problems to better allocate resources and analyze risks.

Data Tables

Data tables organize data in rows and columns.
They can improve the look and feel of spreadsheets, making them easier to use and understand.
Excel includes several tools and predefined table styles.

Analysis ToolPak Add-ins

The Analysis ToolPak is an Excel add-in that provides data analysis tools for financial, statistical, and engineering tasks.

PivotTables and PivotCharts

PivotTables summarize large amounts of data by grouping related data points, allowing for easy analysis and filtering.
PivotCharts are interactive charts that visualize data presented in PivotTables.

Power Query

Power Query is a data extraction and manipulation tool with many data transformation features.
It allows users to clean, combine, and restructure data from various sources.
