If you are just concerned with that team, it is a parameter. If you want to generalize the data to all teams, it is a statistic.
r = ?

The quantity described, the correlation between height and weight for players on the 2010 Brazil World Cup team using data from all 23 players on the roster, is a statistic.
Notation: r (correlation coefficient)
In this case, the quantity described is a statistic. A statistic refers to a numerical summary calculated from a sample of data. In this scenario, the data is obtained from all 23 players on the 2010 Brazil World Cup team.
The correct notation for the correlation between height and weight for players on the 2010 Brazil World Cup team would typically be denoted by the letter "r". Therefore, the notation for this statistic would be "r".
