We will specifically be interested in issues of bias. This is what we mean: thanks to the recent resolution of the Sato-Tate Conjecture in this context, one knows that---roughly---half the Fourier coefficients $a_E(p)$ are positive and half negative. Indeed, the numbers of positive values and negative values look very close:

To study, then, the weighted sums that directly reflect finer statistical issues related to this symmetric distribution, we will be concentrating on weighting functions $p \mapsto g_E(p)$ that have the property that \begin{itemize} \item for all primes $p$, $g_E(p)$ is an {\it odd} function of the value $a_E(p)$, and \item the {\it sum\ of\ local\ data} $$\delta_E(X):=\sum_{p\le X}g_E(p)$$ has---or can be convincingly conjectured to have---a finite mean{\footnote{ See Section {\ref{mean}} below}} relative to multiplicative measure $dX/X$.\end{itemize} In such a context the mean of $\delta_E(X)$ can be interpreted as a {\it bias}!
