A Pareto chart is a specific type of bar graph that represents the frequency of problems or issues in a dataset, arranged in descending order. This allows for easy identification of the most significant factors contributing to a problem, following the Pareto principle, which asserts that roughly 80% of effects come from 20% of the causes.

The choice regarding consecutive points in a run is not applicable to a Pareto chart because a Pareto chart's primary purpose is to present data categorized into distinct issues or causes rather than tracking the sequence or trend of data points over time. In contrast, consecutive points in a run relate more to time series data or control charts that analyze the sequential behavior of a variable.

Relative frequency of occurrence, ordered bar charts, and illustration of priority of issues all align with the core function of a Pareto chart. The relative frequency allows you to see how often each issue occurs, the ordered bar chart visually depicts these frequencies sorted by their values, and the illustration of priority helps to identify which issues should be addressed first based on their significance, illustrating a clear prioritization for improvement efforts.
