“bridging the disciplines…”
• Statistics is taken across disciplines
• Statistics anxiety occurs across disciplines
(e.g., in the humanities, social sciences, and in
classes for pre-service elementary school teachers)
• Fun spans disciplines
Example: “The best lyricists…are using elements of phonetics, linguistics, grammar, semantics, metrics, rhyme, rhythm,
poetics, phonology, communications, sociology, and even the psychology of verbal behavior.” (Davis, 1985, p. ix)
Background from Lesser et al.
in March 2013 J. of Statistics Education
and August 2013 JSE webinar
• fun connects to GAISE
• overview conceptualizations of fun
• 20+ modalities of fun listed
• sources of statistics fun
(e.g., https://causeweb.org/resources/fun/)
considerations for use of fun
Lesser and Pearl (2008)
• Course goal or statistical concept
associated with the item
• Where used (e.g., in class, on website)
• What to do/say/ask before using the fun
item to “set it up”
• What to do/say/ask after using the fun item
let’s illustrate using this cartoon
“It’s a Sign: A Connection between
Correlation and Slope”
(students randomly assigned to include the red part or not)
The correlation coefficient r tells us something about the
strength and linear relationship of a scatterplot of data.
By strength, we mean how tightly the points cluster
around the regression line (i.e., the line of best fit). All
else being equal, a correlation value of r = .7 (or r = -.7)
generally indicates a stronger linear relationship than a
value such as r = .3 (or r = -.3).
The direction of the relationship has to do with the sign of
r. If r > 0, we have positive correlation, which means
higher values of Y are associated with higher values of
X, and lower values of Y are associated with lower
values of X. In other words, X and Y go up and down
together. Such a scatterplot would be described best
with a line of fit that has a positive slope, and indeed this
is always the case: positive correlation happens when
the regression line slope is positive. Likewise, r < 0
means negative correlation, with X and Y moving in
opposite directions from each other, thus suggesting a
line of fit with a negative slope. Finally, a scatterplot with
no real linear trend at all (i.e., r = 0) would have a line of
fit that is horizontal, which means slope of 0. Whether
positive, negative, or zero, the sign of the correlation r is
the same as the sign of the slope of the line.
Here are lyrics to a song (sung to the tune of the familiar
folk tune “Twinkle, Twinkle Little Star” that helped you
learn the alphabet) to help you rehearse and permanently
acquire this fact in your mind:
Correlation Song (lyric © 2013 Lawrence M. Lesser)
Are points near a line, or far?
What’s the correlation, r?
If the fit supports a line,
Its slope and r would share the sign.
Twinkle, twinkle, you’re a star:
Knowing stats will take you far!

inserts” in content readings accessed via LMS
• All students take midterms/finals with
embedded multiple-choice items related to the
(12-14) content readings
• All students asked to take post SATS & SAM

item-randomized experiment
(spring 2014)
(≈ 1000 from larger university)
• Students take pre- and post- SATS; SAM;
and START(Statistical Thinking and Reasoning Test)
• Students see 8 content items with each item
randomized to include fun insert or not
• All students take midterm (3 items) and final
(5 items) with embedded multiple-choice
items related to the content readings
Qualitative Data
• Spring 2013 case study:
Extreme case sampling (fun-experienced
instructor) at medium-sized university, using
multiple data sources: field notes or
transcripts from 5 observations; six 1-on-1
student interviews; end-of-course ratings
and narrative comments from 21 students
• Fall 2013 data: eight 1-on-1 student
interviews from community college
Representative findings
from the qualitative data
• Contextualizing statistics problems in relatable, real-world
examples helped students either understand the concept
and/or remember the context of the content taught
• A fun/humorous approach by the instructor to teaching
statistics made the content memorable and/or tolerable for
those who experienced anxiety over taking statistics
• Almost all students were appreciative (and the exceptions
were just indifferent) of instructors who made an effort to
integrate fun/humor, real-world examples, and/or materials
during instruction to teach concepts
BACKGROUND FOR POLLING QUESTION #5:
One interviewee provided the following response to
this question: What do you think of the use of cartoon,
jokes, songs, and games by the instructor?
“I like them because I’ve been used to mathematics
classes where it’s just strict. It’s like, if you learn the
subject that’s all you can talk about in class. It’s
nice to have just …getting off topic pretty much and
kind of just letting loose for a little. It’s still related to
the subject and you don’t even realize it, it’s just
related to the subject but somehow it eases the
tension that you might think of is associated with
any math course.”

BACKGROUND FOR POLLING QUESTION #6:
How would you interpret the following from another

etc.?:
“…it lightens the mood and it’s more than just
numbers being pounded into your head for an hour
and a half straight. I’ve got other professors that do
that and it’s just, frustrating after a while.”
