How do you convert data into an index?

To convert data into an index, you first standardize the data by selecting a base period or value for comparison. Next, calculate the index value for each data point by dividing the individual data point by the base value and then multiplying by 100. This process allows you to express changes relative to the base, making it easier to analyze trends over time. Finally, you can visualize the index through graphs or charts for clearer insights.
