Based on the Professional Development Opportunities: Desirability Survey Analysis presentation showing the initial stages of a descriptive analysis of the Desirability Survey, complete the table below using complete sentences and according to the following guidelines:

• Column 1 provides the populations for managers and employees.

Professional Development Opportunities: Desirability Survey AnalysisData Sources Three data sources were considered for this presentation: 1. Employee survey to determine desirability of professional development 2. Cost of professional development per employee for various lengths 3. Employee survey to determine professional development delivery preference Data: Desirability Survey . Either ordinal data (item level) or interval data (total) . Survey deployed to 50 participants . Score determined by totaling 10 item scores on survey . For each item, participants could add between 1 and 7 points to their score total (ranging from Strongly Disagree to Strongly Agree) . Maximum score: 70; minimum score: 10 . Higher scores suggest professional development is more desiredData: Professional Development Cost Ratio data Costs collected from vendor for hourly rate per employee ' Collected multiple rates for varying total hours of professional development Data: Delivery Preference Survey . Nominal or categorical data . Surveyed 50 participants (managers and employees) . Asked for mode of delivery: online, in person, or hybrid .
