I have in the LaTeX source file:

usepackage{subcaption}



captionsetup{compatibility=false}



begin{figure}



  begin{subfigure}{0.50textwidth}



  includegraphics[width=0.95linewidth]{RegressionFixedObservedN4451.png}



  caption{Based on the observed data sets}



  label{fig:RegressionFixedObservedN4451}



end{subfigure}%



caption{Regression plot for the fixed condition of the ACT (N = 445). The

 x-axis represents the natural logarithm of the absolute value of the minimum

 residual score belonging to the sequence of 14 consecutive bars with the

 smallest MSE. The y-axis represents the smallest MSE. The top line is the

 line $y = 2x + ln{10}$. The bottom line is the line $y = 2x-ln{10}$. The

 line exactly in between is the line $y=2x$.}



label{fig:observedfixedcondion}



end{figure} 

and the caption is centered. But I want the caption NOT centered. How should I do this?

Please provide a full MWE. By the way, this question has been answered several times on stackexchange: Align Caption to the left

I don't know what caption you are referring to, but this should do the trick:

captionsetup{justification=raggedright,singlelinecheck=false}
