You must first have the z score.
What are the five steps to calculating a one-sample t using SPSS?
,Give this one a try later!
1. Identify population, distribution, assumptions.
2. State null and research hypothesis.
3. Determine statistics for sample and comparison
4. Select critical (alpha) value
5. Make a decision
In a boxplot, what is represented as the highest value?

The highest value is less than/equal to the 75th%tile - 1.5/QR
5 steps to doing a one-tailed test with SPSS...
Give this one a try later!
1. Research hypothesis is directional
2. SPSS analysis is exactly the same as for a 2-tailed.
3. Change decision rule. Reject null and accept research hypothesis if and
only if both (a) result is in the predicted direction, and (b) one half of sig.
value <= alpha.
4. In statistical statement...
- Use half the value of sig. if significant, use ns if not.
- Add (one-tailed)
5. In the English statement, add the direction of the result. Add
"Significantly greater/less than..."
