STAT 217: One Sample Mean Part II Diagram | Quizlet

STAT 217: One Sample Mean Part II Diagram | Quizlet Comparing two means: what if we want to compare the mean of some quantitative variable for the individuals in population 1 and population 2? or compare the average effectiveness of two treatments in a completely randomized experiment? we use the means in the two groups to make the comparisons. Using software, we generated an srs of 12 girls and a separate srs of 8 boys and calculated the sample mean heights. the difference in sample means was then calculated and plotted. The mean and standard deviation of the fe2 group are 9.63 and 6.69; for the fe3 group, the mean is 8.20 and the standard deviation is 5.45. to test the hypothesis that the two means are equal, we can use a t test without assuming that the population standard deviations are equal. In this chapter we deal with statistical inference that corresponds to the comparison of the distribution of a numerical response variable between two sub groups that are determined by a factor.

Important notes • where the measurements obtained in one sample can be shown to depend on measurements in the other sample, paired tests should be used. • a paired t test can be used for dependent interval/ ratio scale data and the sample differences are approximately normally distributed. The formula for comparing the means of two populations using pooled variance is where and are the means of the two samples, Δ is the hypothesized difference between the population means (0 if testing for equal means), s p 2 is the pooled variance, and n 1 and n 2 are the sizes of the two samples.
