* A hypothesis = a testable prediction
* A statement
* The aim of the study
* Purpose of study
* H1, H2, H3
* Where is it at?
* Usually within the last 1-2 paragraphs before the Method section
* What if I have Research Questions?
* Make them into statements
* What if I have more than one hypothesis?
* “As such, we hypothesized that the younger cohort would
demonstrate lower overall quantities of use and lower rates of
symptoms associated with dependence.”
* Elementary age children consume less caffeine and have fewer
frequency of caffeine dependence than high school age children.

presence and strength of specific
Relationships/Associations
* Variables
* Hypothesis may cite positive or negative correlation.
* The greater _______, the more likely _______ will occur
* Lower incidences of _______ will lead to lower incidences of ______
* No Manipulation
* Experimental
* Anticipating cause and effect
* Independent and Dependent Variables
* Manipulation
* Experimental Group and Control Group
* Placebo

* Population = all
* Sample = a section (hopefully representative)
* Who is identified within the hypothesis?
* Who are the participants?
* Total number
* Demographic information
* Interpret the percentages
* For 10th graders, 88% reported their ethnicity as Caucasian,
3% Asian American, 3% Hispanic/Latino, 1% American Indian,
and 5% multiracial or other. On average, 34% of students in
the 3 school districts are enrolled in the free lunch program.
* An overwhelming majority of 10 grade participants identified
as Caucasian ethnicity. Additional ethnicities included Asian
American, Hispanic, American Indian, and multiracial. About a
third of the 10th graders met income requirements for the free
lunch program at school.

* Citing rising obesity rates, school districts are increasingly faced with
decisions about limiting the sale of soft drinks to students. Recently,
some national beverage companies have agreed to end sales of all sodas
in elementary schools and limit sales in high schools to only diet sodas
and other low calorie beverages by the year 2010.1 Yet, excessive
consumption of certain sodas, including diet sodas, also means increased
caffeine intake. Caffeine, the only licit psychoactive drug available to
minors, may have a harmful impact on students’ health, academic
performance, and personal adjustment. This pilot study investigated
naturalistic patterns of youth caffeine intake and potential negative
psychological correlates (ie, depression, anxiety) of caffeine use. Both
elementary and high school students were included to examine how
caffeine use and its effects differed across ages that may have quite
different levels of autonomy over and understanding of caffeine use.
* Despite growing concern of child and teen obesity and potential
unhealthy effects of excessive caffeine use among school age youth,
caffeine consumption among elementary and high school age students
continues to grow. Because of this concern, it is important to examine
side effects of caffeine use among elementary and high school age
students (Lubee & Bell, 2009).

*Must cite source when
*Use direct quotes (but no direct quotations allowed for
our assignment)
*Paraphrase
*Only cite the source you read
*
*If using only one source, can cite at end of paragraph
*Format is:
*One author = (Author’s Last Name, Year)
* (Williams, 2013)
*Two authors = (Last Name & Last Name, Year)
* (Jones & Smith, 2012)
*3-5 authors
*First paragraph= (Last Name, Last Name, Last Name, Year)
* (Waters, Burton, & Andrews, 2011)
*Paragraphs after that = (Last Name
* (Waters et. al., 2011)
et. al., year)
*6+ authors = (First author’s last name et. al., year) for
every paragraph
* (Jackson et. al, 2010)
