The Findings Pertaining to Problem Status
In the study, the students were subjected to “Mathematical Thinking Scale” before and after the course of “Problem
Solving in Mathematics”. Whether the data were suitable for normal distribution was determined before the analysis of
the data obtained. Normality test of the Xi observations of n unit, which was randomly selected from the population
exhibiting normal distribution, is obtained with W test statistics. W test statistics shows difference at the interval of
0
