\begin{slide}
\begin{itemize}
\item What we do is divide range of continuous parameters
$\{$such as $(0\le\theta\le 2\pi)$ in $(1+p\cos\theta)/2\pi$
polarization distribution$\}$ into $M$ small bins.  

\item $M$ should be so large that
\begin{description}
\item{$\bullet$} (a) probability of two events in a given experiment
falling in same bin is zero.
\item{$\bullet$} (b) the theoretical $p_i$ is constant over each bin.
\end{description}

\item then we have $M$ observations---each with one of two results:

\begin{description}
\item{$\bullet$} success---1 event in bin
\item{$\bullet$} failure---0 events in bin
\end{description}
\end{itemize}
