data1 =
  {{1, 8, 9, 1}, {2, 2, 8, 1}, {3, 8, 9, 2},
   {4, 3, 7.5, 2}, {5, 3, 7.5, 1}};

Module[{
  labels =
   Style[#, Bold] & /@
    {"Test", "Variable 1", "Variable 2", "Result "},
  minResult = Min[data1[[All, 4]]],
  maxResult = Max[data1[[All, 4]]]},
 Graphics3D[{
   AbsolutePointSize[8],
   {ColorData["TemperatureMap"][
       Rescale[#[[-1]], {minResult, maxResult}]],
      Point[Rest[#]]} & /@
    data1},
  BoxRatios -> {1, 1, 1/GoldenRatio},
  Axes -> True,
  AxesLabel -> Rest[labels],
  PlotLabel -> Style["TEST RESULTS\n", Bold],
  ImageSize -> 400]]

Or with some embellishments:

Module[{
  labels =
   Style[#, Bold] & /@
    {"Test", "Variable 1", "Variable 2", "Result "},
  minResult = Min[data1[[All, 4]]],
  maxResult = Max[data1[[All, 4]]]},
 Panel[
  Column[{
    Graphics3D[{
      AbsolutePointSize[8],
      {ColorData["TemperatureMap"][
          Rescale[#[[-1]], {minResult, maxResult}]],
         Tooltip[
          Point[Rest[#]],
          "Test " <> ToString[First[#]] <>
           "\nVar = " <>
           ToString[#[[{2, 3}]]] <>
           "\nResult = " <>
           ToString[Last[#]]]} & /@
       data1},
     BoxRatios -> {1, 1, 1/GoldenRatio},
     Axes -> True,
     AxesLabel -> Rest[labels],
     PlotLabel -> Style["TEST RESULTS\n", Bold],
     ImageSize -> 400],
    Grid[Prepend[data1, labels],
     Frame -> All,
     Background -> Lighter[Gray, .75]]},
   Alignment -> Center]]]

I would like to see how the test results vary as the variables change. Perhaps ListPlot is not what I want, it was my thought just to see something similar to what I can do in a Excel graph.
