A researcher was interested in
learning about the effect of caffeine consumption on problem
solving. To examine this relationship, participants were randomly
selected and assigned to one of four conditions: no caffeine
consumption, 100 mg dosage of caffeine, 200 mg dosage of caffeine,
or 300 mg dosage of caffeine. The participants were then asked to
solve as many anagrams* as possible in a 5 minute period. The
results of the study are presented below.
*Anagrams are word puzzles that
are solved by rearranging the letters so that each letter is used
exactly once to create a new word, for example: No Eagle in Jail =
Angelina Jolie or Balk Tables = Basketball.

A researcher is interested in looking at the effect of sleep and
caffeine on physical performance. The researcher has each subject
perform a series of 6 tests across a number of week. The researcher
alters the amount of sleep the subject should receive (8 hours, 6
hours, and 4 hours) while also altering whether they drink coffee
in the morning or they do not. These two factors are completely
crossed to create the six conditions. Eight subjects were recruited
for...

A researcher is interested in the effects of sleep deprivation
and caffeine intake on mood. Participants were randomly assigned to
a sleep condition (normal or deprived) and a caffeine condition (0
cups, 2 cups, or 4 cups). After the manipulations, mood was
measured (such that higher numbers indicated better mood). The
results were as follows:
Normal

A researcher investigated the effect of caffeine on performance
on a test of attention. Twenty people were given regular black
coffee, twenty people were given espresso, twenty people were given
soda, and twenty people were given an energy drink. Afterwards,
they were all given tests of attention. What is the 〖df〗within?
What is the 〖df〗between? What is the critical value of F for
the 0.05 significance level (using Figure 12.6. F-table for use
with ANOVA)?
〖df〗within = number of participants...

Another researcher is interested in how caffeine will affect the
speed with which people read but decides to include a third
condition, a placebo group (a group that gets a pill that looks
like the caffeine group does, but it does not contain caffeine).
The researcher randomly assigns 12 people into one of three groups:
50mg Caffeine (n1=4), No Caffeine (n2=4), and Placebo (n3=4). An
hour after the treatment, the 12 participants in the study are
asked to read from...

A researcher was interested in the effects of caffeine
on sleep. She measured how many minutes it took for ten
participants to fall asleep. Half of the participants drank a liter
of caffeinated soda before going to sleep while the other half were
only allowed to drink water. Summary data of minutes are presented
below. Did the caffeine increase the length of time it took to fall
asleep (a =.05)?

A researcher is interested in the amount of soda consumption
for males and females compared to the population. Suppose that the
researcher selects a sample of n = 36 male undergraduates and a
sample of n = 25 female undergraduates. On average, males reported
consuming M = 2.45 drinks per month, while females averaged M =
1.47 drinks per month. Assuming an overall average for
undergraduates of μ= 1.85 drinks per month with a standard
deviation σ=1.2, please answer the...

A researcher is interested in studying the effect that the
amount of fat in the diet and amount of exercise has on the mental
acuity of middle-aged women. The researcher used three different
treatment levels for the diet and two levels for the exercise. The
results of the acuity test for the subjects in the different
treatment levels are shown below.

A researcher is interested in looking at the effects of Gatorade
consumption on energy use during exercise. To look at this, the
researcher split subjects into three groups: No Gatorade, 2 pints
of Gatorade, and 4 pints of Gatorade. Subjects were asked to
exercise and VO2 max values were recorded. The researcher also was
interested in looking at the differential effects of gender. The
following data for 48 subjects was collected: Can someone do this
in SPSS?
