1) The best way to organize survey data in Excel is

Select one:

a.set up so each respondent get his/her own column, and the data fields for each question are in the different rows.

b.make data entries like "Agree" and "Strongly Disagree," and donotuse numbers.

c.by respondent last name, alphabetically.

d.use highly abbreviated, super-short variable names when naming each factor in the data.

e.none of the above.

2) If, using a t-test of difference between two unrelated sample means, you calculate that two samples have a statistically significant difference between their means at a level of p0.05, this means

Select one:

a.there is a 5% chance that thedifference between means is in fact a result of random chance, and not a real difference.

b.The means are actually the same, and there is no significant difference between the two samples.

c.The two samples donotdiffer significantly based on the factor under study.

d.One sample probably contains outlier (extreme value) data which is throwing off the calculation of the p-level of significance.

e.None of the above.

3) The t-test null hypothesis (H0) always states

Select one:

a.As the mean of one sample increases, the mean of the other sample decreases.

b.One sample mean is greater than the other sample mean.

c.There is a statistically significant difference between the means of the two samples.

d.There is no statistically significant difference between the means of two samples.

e.None of the above.
