Data Analysis in Excel Basics

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.
