Study Notes
Formulas
- Arithmetic Operations: Excel formulas can perform basic arithmetic operations like addition, subtraction, multiplication, and division using the corresponding operators (+, -, *, /)
-
Functions: Excel has a wide range of built-in functions for tasks like:
- SUM(range): adds up a range of cells
- AVERAGE(range): calculates the average of a range of cells
- COUNT(range): counts the number of cells in a range that contain numbers
- IF(logical_test, [value_if_true], [value_if_false]): tests a condition and returns one value if true and another value if false
-
Cell References: Excel formulas can reference cells using:
- Absolute references (e.g., A1): references a specific cell
- Relative references (e.g., A1:A10): references a range of cells
- Mixed references (e.g., $A1): references a specific column and relative row
-
Error Handling: Excel formulas can handle errors using:
- IFERROR function: returns a value if an error occurs
- IFBLANK function: returns a value if a cell is blank
Charts
-
Chart Types: Excel offers various chart types, including:
- Column charts: compares categorical data across different groups
- Line charts: shows trends over time or categories
- Pie charts: displays how different categories contribute to a whole
- Bar charts: compares categorical data across different groups
-
Chart Elements: Excel charts consist of:
- Plot Area: the area where the chart is drawn
- Axes: the horizontal and vertical lines that provide context to the chart
- Legend: a key that explains the data series
-
Customizing Charts: Excel allows customizing charts by:
- Changing the chart type
- Adding or removing data series
- Modifying axis labels and titles
- Applying different themes and styles
Macros
- What are Macros?: Macros are sets of automated commands that can be recorded or written in VBA (Visual Basic for Applications) to perform repetitive tasks
-
Recording Macros: Excel allows recording macros by:
- Performing a series of actions while the macro recorder is on
- Stopping the recorder and saving the macro
- VBA Editor: The VBA Editor is a development environment where macros can be written and edited using VBA code
-
Macro Security: Excel has built-in security features to prevent malicious macros from running, including:
- Macro settings in the Trust Center
- Digital signatures for trusted macro authors
Data Analysis
-
Data Analysis Tools: Excel provides various data analysis tools, including:
- PivotTables: summarizes and analyzes large datasets
- Power Query: imports, transforms, and loads data from various sources
- Power Pivot: creates data models and performs advanced data analysis
-
Data Visualization: Excel offers various data visualization tools, including:
- Conditional Formatting: highlights important data trends and patterns
- Sparklines: creates small, inline charts to visualize data
- Treemaps: displays hierarchical data as nested rectangles
-
Statistical Functions: Excel provides various statistical functions, including:
- AVERAGE: calculates the average of a dataset
- STDEV: calculates the standard deviation of a dataset
- CORREL: calculates the correlation coefficient between two datasets
