What should a Data Analyst create to visualize salary ranges in equal intervals?

Creating bins is the most effective way to visualize salary ranges in equal intervals. In Tableau, bins allow you to group continuous numerical data into discrete ranges, making it easier to analyze and visualize distributions. For salary data, you can define a bin size—such as $500 or $1,000—and Tableau will automatically organize the data into these defined intervals. This approach helps in identifying how many salaries fall within each interval, allowing for a clear representation of the distribution of salaries across the defined ranges.

Using bins provides a straightforward way to create histograms, which visually depict frequency distributions, making patterns and trends more accessible for analysis. This is crucial for a data analyst when interpreting salary data, as it provides insights into the compactness or spread of salary distributions.

Reference lines are useful for highlighting specific values on a chart but do not create intervals. Calculated fields allow for custom calculations but are not designed for grouping data into ranges. Parameters provide flexibility and interactivity but would not effectively create the ranges necessary for this visualization type. Thus, bins stand out as the ideal choice for visualizing salary ranges in equal intervals.
