We want to compare the performances of two javelin throwers in one competition. Throws of Alex and Martin (in meters) are recorded in the following table. Calculate the coefficient of variation for each set of results and determine, which of the athletes has more balanced performance. I.e. choose the name of the athlete with more balanced performance and with the correct coefficient of variation (\( \% \)) of his throws. The coefficient of variation is rounded to two decimal places.
\[
\begin{array}{|c|c|c|c|c|} \hline \textbf{Alex} & 78.95 & 83.32 & 86.14 & 84.46 \\\hline \textbf{Martin} & 84.66 & 83.63 & 76.83 & 83.23 \\\hline \end{array} \]
Alex: \( 3{.}20\,\% \)
Alex: \( 27{.}99\,\% \)
Martin: \( 4{.}52\,\% \)
Martin: \( 23{.}52\,\% \)
