Hello,

It’s understandable that you’re feeling uncertain about the data analysis part. While it’s unfortunate that there hasn’t been specific teaching or guidance in your course content, don’t worry—I’m here to assist you!

Diagrammatic representation is a powerful way to convey information visually. Let’s focus on the second part of your query related to presenting average length of service in a month-year format.
To achieve this, we’ll create a chart that displays the average length of service over time (months and years).
