Description
Mathematics word problems can be particularly difficult,
especially for primary-grade children. A recent study investigated a
combination of techniques for teaching students to master these problems
(Fuchs, Fuchs, Craddock, Hollenbeck, Hamlett, & Schatschneider, 2008). The
study investigated the effectiveness of small-group tutoring and the
effectiveness of a classroom instruction technique known as “hot math.” The hot
math program teaches students to recognize types or categories of problems so
they can generalize skills from one problem to another. The following data are
similar to the results obtained in the study. The dependent variable is a math
test score for each student after 16 weeks in the study.
Check your data
entry carefully! It is easy to lose almost all the points on this homework
assignment if you mistype a number – as many subsequent statistics and analyses
will be incorrect!
Output
1)
Paste the necessary output for this analysis (both descriptive and inferential)
from jamovi. Provide tables with APA-style titles.
2)
Paste an appropriate graph from jamovi. Provide your graph with an APA-style header.
Hint: this graph should display all
possible combinations of groups.
Non-APA portion
3) What
are the null hypotheses for this study? What are your decisions about each?
What are your rationales for those decisions?
APA portion
4)
Write an APA style report of your findings. Your report should include each of
the following, with no errors of APA style or formatting. Round p-values to three decimal places; all
other values to two.
·
a
statement about the significance (or not) of each omnibus test statistic
·
the
value of each omnibus test statistic with their degrees of freedom
·
the
precise p-value as reported by jamovi
for each omnibus test statistic
o
e.g.
not p < .05 but p = .015
o
unless
jamovi reports p = .000, in which
case you must use p < .001
·
a
measure of effect size (partial eta-squared) for each omnibus test
·
for
each main effect, either a) a statement which makes clear the direction of any
significant differences or b) a statement that a given difference is not
significant
·
for
the interaction effect, either a) a statement which describes the nature of a
significant interaction or b) a statement that describes what it means that
there is no significant interaction
·
In
your reporting, you should include descriptive statistics, either in-text
(being careful to use marginal means as appropriate) or as an in-text reference
to the table of descriptive statistics table
