I'm attempting something that should be very simple. However I've just started learning today and and can't quite understand.
This is my code so far:
Public Sub getCellData()
   Dim wb As Workbook: Set wb = ThisWorkbook
   Dim ws As Worksheet: Set ws = wb.Sheets(1)
   Dim rng As Range: Set rng = ws.Range(Cells(1, 2), Cells(4, 2))
   Debug.Print rng
End Sub
The data that I'm working with is this:

I keep getting the "Run-time error '13': Type mismatch" I googled the error and I'm still unsure of how to fix this. I want to print the variable rng in the immediate window.
Range is an object, not a value. To output the values, you can iterate the Range. Another way is to use the Transpose function on a single row or column and then Join to get a String value of the array of values within the Range.
Sample code:
Public Sub getCellData()
    Dim wb As Workbook: Set wb = ThisWorkbook
    Dim ws As Worksheet: Set ws = wb.Sheets(1)
    ' you need to prefix Cells with ws. to clarify the reference
    Dim rng As Range: Set rng = ws.Range(ws.Cells(1, 2), ws.Cells(4, 2))
    ' you cannot debug print the object itself
    'Debug.Print rng
    ' iterate the range
    Dim rngCell As Range
    For Each rngCell In rng
        Debug.Print rngCell.Value
    Next rngCell
    ' use the Transpose function for a single row or column
    Dim strData As String
    Dim wsf As WorksheetFunction: Set wsf = Application.WorksheetFunction
    strData = Join(wsf.Transpose(rng.Value), ",")
    Debug.Print strData
End Sub
Note I updated your Set rng = ... to:
Set rng = ws.Range(ws.Cells(1, 2), ws.Cells(4, 2))
And added ws. as a prefix to Cells in order that the references were explicitly defined.
