Case Study: Employee Engagement $($Taken from Predictive HR Analytics Chapter $5,$ Example $4.)$

Learning Question: Do employee engagement levels significantly differ depending on location?

Given that engagement is such a key behaviour for organizations to want to develop, it is important to know whether there are any team$-$level factors that might $$predict$$ engagement. The data set for this case study includes a combination of team$-$level HR metrics, employee demographic data and engagement survey data. There are $29,976$ employees in these functions across the UK and these employees are organized into $927$ teams or employee units. The $30$ variables in the data set include the following:

Run a t$-$test with the team$-$level engagement results as the dependent variable $($column S$),$ comparing two regional and geographical groups in the organization $($or two samples$)$ namely $$London$$ or $$Not London$($Column H$),$ on their engagement survey results. This is testing the strongly held belief $($held by senior management at the organization$)$ that people in regional offices are less engaged than those based in the $$dynamic$$ London branches. We want to test whether teams in the regional offices are less engaged than teams in the London office.
