Avoid automatic centering of caption [duplicate]

Question

I have in the LaTeX source file:

\usepackage{subcaption}

\captionsetup{compatibility=false}

\begin{figure}

  \begin{subfigure}{0.50\textwidth}

  \includegraphics[width=0.95\linewidth]{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}
