Hi John

How about this?

y1 = RandomReal[ NormalDistribution[ 0, 1 ] ]

y2 = RandomReal[ NormalDistribution[ 0, 1 ] ]

y3 = RandomReal[ NormalDistribution[ 0, 1 ] ]

y4 = RandomReal[ NormalDistribution[ 1, 1 ] ]

y5 = RandomReal[ NormalDistribution[ 1, 1 ] ]

y6 = RandomReal[ NormalDistribution[ 1, 1 ] ]

ListPlot[{{{1, y1}, {1, y2}, {1, y3}}, {{2, y4}, {2, y5}, {2,
y6}}}, PlotStyle -> {PointSize[ 0.02 ]}]

sample1 = Table[ {1, RandomReal[ NormalDistribution[ 0, 1 ] ]} , {20}]

sample2 = Table[ {2, RandomReal[ NormalDistribution[ 1, 1 ] ]} , {20}]

ListPlot[{sample1, sample2}, PlotStyle -> {PointSize[ 0.02 ]}]

Cheers

Barrie
