I cannot get this code to work. Both HAL and one2three are a 22x1 array. I need to put them on a boxplot but cannot get it to work. The group part was just added but nothing is coming out with that either. They are both the same length and I keep getting an error message.
HAL = Project1Data(2:23,1);
one2three = Project1Data(2:23,2);
group = [ones(size(HAL)); 2*ones(size(one2three))];
boxplot([HAL, one2three],group);
title("Lotus Scores");
xlabel("Lotus Group");
ylabel("Score (0-10)");
I added the data below, titled Project_1_Data.

Turn the first input into a vector,
boxplot([HAL; one2three],group);
% ^
or use a matrix without a grouping variable,
HAL = Project1Data(2:23,1);
one2three = Project1Data(2:23,2);
boxplot([HAL, one2three]);

Not using the grouping variable leads to this
Error using boxplot>straightenX (line 898)
'X' parameter must be a numeric vector or matrix.
Error in boxplot (line 274)
[xDat,gDat,origRow,xlen,gexplicit,origInd,origNumXCols] =
straightenX(x,g);
Error in Project_1 (line 4)
boxplot([HAL, one2three]);

So, what is X if it's not a vector or matrix?
The first two lines below indicate that HAL and one2three are column vectors of equal length.
The third line horizontally concatenates those two column vectors to make a matrix.
HAL = Project1Data(2:23,1);
one2three = Project1Data(2:23,2);
boxplot([HAL, one2three]);
If that's not the case for your data, provide more info on the inputs you're using to boxplot.
