To show how many customers must wait each night for a table, and how long they wait, which tool would work best?

Question

BlackTom AI · Accepted Answer

The question asks which tool best shows how many customers must wait each night for a table and how long they wait. 
Option 1: Histogram. A histogram is designed to display the distribution of a continuous variable, such as wait times, by grouping data into bins. It effectively shows the frequency of different wait durations and can illustrate the overall shape of the waiting time distribution across nights. This aligns with the goal of showing both counts (how many) and timing (how long). 
Option 2: Spaghetti diagram. This tool maps the physical flow of people or items in a process to identify unnecessary movement and complexity. It is useful for analyzing layout and movement paths, not for recording wait counts or wait times over nights. Therefore, it does not directly answer the question about wait amounts and durations. 
Option 3: Pareto chart. A Pareto chart combines bars in descending order of frequency or impact with a cumulative line to highlight the most significant factors. While it’s helpful for prioritizing issues, it does not inherently present the full distribution of wait times or the exact counts per night over a period. It’s more about prioritization than full distribution visualization. 
Option 4: Checklist. A checklist is a simple list used to ensure steps or items are completed, not a data-visualization tool. It would not convey the distribution of wait times or the number of customers waiting across nights. 
In summary, among the given options, the histogram best fulfills the need to display both the number of waiting customers and their wait durations in a distribution over time, while the other tools serve different purposes (flow analysis, prioritization, or task completion) and do not directly provide the requested visualization.
