Common Data Issues and How to Fix Them

Missing Values: Missing values are a common problem in financial datasets. You can handle them in several ways:
- Deleting Rows/Columns: If a small number of rows or columns have missing values, you might choose to delete them. However, be cautious when deleting data, as it can introduce bias or reduce the statistical power of your analysis.
- Imputation: Imputation involves replacing missing values with estimated values. Common imputation methods include:
  - Mean/Median Imputation: Replace missing values with the mean or median of the non-missing values in the column. This is a simple and quick method, but it can distort the distribution of the data if there are many missing values.
  - Forward/Backward Fill: Replace missing values with the previous or next valid value in the column. This is useful for time-series data where values are likely to be correlated over time.
  - Interpolation: Estimate missing values based on the values of neighboring data points. This is suitable for time-series data with smooth trends.
- Using Formulas: Excel formulas like IFERROR can help you handle missing values dynamically. For example, you can use IFERROR(A1/B1, 0) to return 0 if the division results in an error due to a missing value.
Inconsistent Formatting: Ensure that data is consistently formatted across the dataset. This includes:
- Dates: Standardize date formats (e.g., MM/DD/YYYY, DD/MM/YYYY) using Excel's 'Format Cells' option.
- Numbers: Ensure consistent decimal places, currency symbols, and thousand separators.
- Text: Trim leading and trailing spaces using the TRIM function. Convert text to uppercase or lowercase using the UPPER or LOWER functions, respectively.
Duplicate Entries: Identify and remove duplicate rows using Excel's 'Remove Duplicates' feature in the 'Data' tab. Be cautious when removing duplicates, as they might represent valid data points.
Outliers: Identify and handle outliers, which are extreme values that deviate significantly from the rest of the data. Outliers can distort statistical analyses and visualizations. You can identify outliers using statistical techniques like the interquartile range (IQR) method or by visualizing the data using box plots.
