摘要：By means of ANOVA variance analysis we have studied the size and frequency of deviation of the real values of statistic characteristic from the calculated theoretical values, as well as the level of dependence or independence of these variations of the group factor. Variance analysis applies especially when data are generated by selective research. Statistic poll that I personally conducted on Romanian seaside balneary tourism has mainly investigated the attitude, opinions and motivations of balneary tourism demand on Romanian Black Sea coast. One of the objectives of this partial statistic research on seaside hydro tourism is represented by the duration of a balneary vacation that is influenced by the age of tourists as well. In order to evince the relation between the two variables above we have processed the data of the sampling, we have sorted and grouped tourists by their age and duration of vacation and then we have applied the variance analysis to verify and demonstrate that balneary tourists’ age induces the duration of a balneary vacation.
