STATISTICAL TECHNIQUE IN REVIEW
Most studies describe the subjects that comprise the study sample. This description of the sample
is called the sample characteristics which may be presented in a table or the narrative of the
article. The sample characteristics are often presented for each of the groups in a study (i.e. experimental
and control groups). Descriptive statistics are used to generate sample characteristics, and
the type of statistic used depends on the level of measurement of the demographic variables
included in a study (Burns & Grove, 2007). For example, measuring gender produces nominal level
data that can be described using frequencies, percentages, and mode. Measuring educational level
usually produces ordinal data that can be described using frequencies, percentages, mode, median,
and range. Obtaining each subject’s specific age is an example of ratio data that can be described
using mean, range, and standard deviation. Interval and ratio data are analyzed with the same type
of statistics and are usually referred to as interval/ratio level data in this text.

management of postpartum fatigue. Applied Nursing Research, 16(1), 38–45.
Introduction
Troy and Dalgas-Pelish (2003) conducted a quasi-experimental study to determine the effectiveness
of a self-care intervention (Tiredness Management Guide [TMG]) on postpartum fatigue. The study
subjects included 68 primiparous mothers, who were randomly assigned to either the experimental
group (32 subjects) or the control group (36 subjects) using a computer program. The results of
the study indicated that the TMG was effective in reducing levels of morning postpartum fatigue
from the 2nd to 4th weeks postpartum. These researchers recommend that “mothers need to be
informed that they will probably experience postpartum fatigue and be taught to assess and manage
this phenomenon” (Troy & Dalgas-Pelish, 2003, pp. 44-5).
Relevant Study Results
“A total of 80 women were initially enrolled [in the study] . . . twelve of these women dropped out
of the study resulting in a final sample of 68.” (Troy & Dalgas-Pelish, 2003, p. 39). The researchers
presented the characteristics of their sample in a table format for the experimental and control
groups (see Table 1). The researchers found no significant differences between the control and
experimental groups for any of the demographic or attribute variables.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
