Fitness and Health Center Evaluation by Resigned Female Members

In the evaluations and statistical analyses presented here we examine the question to what extent are the evaluations of a fitness studio, by females dropping out from their contract, age-dependent. In other words: do studio evaluations – that probably have played a role in the quitting decision – have a different basis in older women in relation to younger women? According to the life stages, do other needs and therefore other preferences regarding the studio conditions play a role here?

A total of 164 women, who had terminated their contract with a fitness studio, were questioned. The survey was conducted as a telephone inquiry about their actual decision. Overall, it is found that only a few of the reasons offered in the survey are also indicated in significant frequency as important for the quitting decision. On the whole, the various aspects of the studio offer and its surroundings were largely rated as “good”, the mean values range around the value 2. The respondents particularly expressed their appreciation for the trainers (friendliness, helpfulness, competence), followed by opening hours, trial training and first impression. The membership costs and individual aspects such as spaciousness, music and ventilation are evaluated more critically, if not really badly. As regards the respondents’ age, there are only minor evaluation differences among the age categories.

These small differences in age have, depending on the item evaluated, very different directions. The correlations between age and studio evaluation are usually weak up to practically non-existent and in most cases also clearly not significant. Weak but distinguished from chance effects appear in the characteristics endurance training offer and parking facilities.

The growing business of professional sports has lead to an increasing demand for effective metrics quantifying factors leading to team success, and evaluating individual player contributions to that success. In the sport of hockey the advancement of analytics has lead to a decline in the use of goal-based metrics, and an increased reliance on shot-based metrics. I tested assumptions behind this trend by using statistical modeling of 10 years of NHL data to directly compare the effectiveness of goal versus shot-based metrics at predicting team success, and comparative hypothesis testing to determine how well goals and shots quantify player contributions to team success. Goal-based models consistently outperformed their shot-based analogs. Models of team goal differential successfully predicted winning % during the 2015-16 season, while shot differential did not. Goal-based metrics (i.e. relative plus-minus/minute of ice time) were also better than shot-based metrics (i.e. relative Corsi/minute of ice time) for evaluating individual player contributions to team winning %. These results show that team and individual performance is not correlated with all shots, but only those shots effective enough to result in goals. These results will lead to more effective evaluation of individual players, and better understanding and prediction of those factors leading to team success.
