Two random samples (15 scores each) of data have been taken from the student "raw score" or true population with independent variable conditions: sample1 (water consumption) and sample2 (no water consumption) and given a memory assessment [test]. Experimental hypothesis: Depriving students of water for a week will affect memory ability. Next, compute the "n," sample mean, and estimated population variance and standard deviation using SPSS for both samples and conduct an independent two-sample t-test (with summary) to analyze the data/results...
