Question 1:
Some people are more susceptible to hypnosis than others. Peoplewho are highly suggestible have a vivid imagination and fantasylife. This has led researchers to hypothesize that the ability torecall dreams will also be affected by hypnotic susceptibility(HS). Dr. Flowers wanted to test this hypothesis. Using theStanford Scale of Hypnotic Susceptibility, she assignedparticipants to low, medium, and high susceptibility groups. Dr.Flowers asked all participants to keep a dream diary. At the end of1 month, the diaries were collected and Dr. Flowers counted thenumber of dreams each person had recalled.
What is the alternative research hypothesis for this study?
What is the null research hypothesis for thisstudy?
What is the first word in the alternative statistical hypothesisfor any experiment with three levels of a single IV?
What is the null statistical hypothesis for the study of dreamrecall among groups with different levels of hypnoticsusceptibility?
?lowHS = ?medHS = ?highHS?lowHS = ?medHS = ?highHS
?lowHS ? ?medHS ? ?highHS?lowHS ? ?medHS ? ?highHS
In SPSS, analyze the data in the table using a one-wayANOVA.
Low HS | Medium HS | High HS |
4 | 14 | 22 |
9 | 12 | 26 |
6 | 3 | 13 |
8 | 26 | 20 |
14 | 15 | 27 |
16 | 19 | 19 |
8 | 17 | 16 |
10 | 5 | 14 |
Use the results in the output box labeledDescriptives to complete the following chart,which you will then use to answer the following 6 questions.
| Low HS | Med HS | High HS |
Mean | | | |
SD | | | |
What is the mean of the low HS group? (2decimal places)
What is the mean of the medium HS group? (2decimal places)
What is the mean of the high HS group? (2decimal places)
What is the SD of the low HS group? (2 decimalplaces)
What is the SD of the medium HS group? (2decimal places)
What is the SD of the high HS group? (2 decimalplaces)
Using the results in the output box labeled ANOVA, answer thenext two questions.
What is the F ratio reported in the source table? (2decimal places)
What is the p value reported in the source table?(located in the column labeled Sig)(3 decimalplaces)
In SPSS, conduct a post hoc test using Tukey's HSD to determinewhich groups differ significantly.

Write a complete APA-style conclusion.
This is a template you will use to report the results ofExperiment 1 of this study in the same format in which you wouldwrite the Results section of an APA-style lab report or journalarticle:
Based on a one-way ANOVA conducted in SPSS (Version 25),hypnotic susceptibility (HS) does /does not havean effect on the number of dreams recalled, F(#,##) = ###,p= ###. Tukey’s post hoc tests revealed that fewer/ the same number of / more dreams are recalled in thehigh HS condition (M= ###) than / as inthe low HS condition (M= ###), p= ###. There isa / no significant difference between the numberof dreams recalled in the low HS condition and the medium HScondition (M= ###), p= ###. There is alsoa / no significant difference between the numberof dreams recalled in the medium HS condition and the high HScondition, p= ###. Therefore, the results confirm thathigh HS is associated with fewer / the same number of /more dreams being recalled when compared to those with lowHS.
