CHAPTER 2 Summarizing and Graphing Data 1) Introduction In this chapter we will look at methods of descriptive statistics. We will concentrate on how to condense and organize data. We will look at the following: 1. Collect raw data 2. Organize data in a frequency distribution ...

actual percentage of people who received the flu vaccine did not fall between the ranges as predicted by the margin of error. Bennett, Briggs, and Triola (2009) stated, “The margin of error in a statistical study is used to describe the range of values or confidence interval, likely to contain the population...
Frederick Sakon The text states that random errors occur due to random and unpredictable events during the measuring process (Bennett, Briggs, & Triola, 2009). For example, if an individual is pouring three teaspoons of medicine into a medicine cup, the measurement will be slightly off every time....
186,000 viewers each paid 50 cents to call a “900” telephone number with their opinion about keeping the United Nations in the United States(Mario F. Triola, 2010). The results showed that 67% of those who called were in favor of moving the United Nations out of the United States. However, in general view...
Statistics is defined by Bennett, Briggs, & Triola (2009), as “the science of collecting, organizing, and interpreting data” (p. 1). Almost every profession uses statistics in some way to guide in making good decisions based on current research. The nursing profession relies heavily on current research...
validity of results. Primary data is described as data observed or collected directly from first-hand experience (Triola, 2010). Secondary data is published data, or data collected by others (Triola, 2010). Primary data is preferred in research because the knowledge is obtained first-hand, where secondary...
HCS 438 October 3, 2011 Howard Rubin Workplace Statistics Statistics is everywhere in a person’s daily life. As Stated by Bennett, Briggs, and Triola (2009), “you’ll be hard-pressed to think of any topic that is not linked with statistics in some important way” (p. 2). The hospital, which I am, employed...
The statistical analysis of this experiment involves matched pairs, where there is a relationship or pairing between two dependent samples (Triola & Triola, 2006). This experiment will test the effectiveness of chia seeds in reducing blood glucose levels; the pre-trial lab samples will be paired...
Information Lynda Gruenewald-Schmitz HCS/438 June 17, 2013 Amber Krasny Uses of Statistical Information According to Bennett, Briggs & Triola (2009), descriptive statistics transforms data into a picture of information that is readily understandable using measures such as mean, median, mode...
“we determine statistical significance by using probability to quantify the likelihood that a result may have occurred by chance,” (Bennett, Briggs, Triola. 2009, p. 235). Testing a hypothesis is required for all professionals who wish to practice in an evidence-based system. The left and right tailed...
means of sample collection, providing equal chance to the members of a given population being signified. Populations Populations, as defined by Triola and Triola (2006) are “a complete collection of all elements (scores, people, measurements and so on) to be studied. The collection is complete in the sense...
from a nationally distributed normal population, the distribution of sample mean can be used as an unbiased estimator of the population mean (Triola, M. M., & Triola, M. F., 2006 p274).Since the number of samples are greater than 30 (n=40), and an assumptions that the distribution is precise (no significant...
was observational and measured continuous data sets including the height, weight, age, and gender of the participant's children (Bennett, Briggs, & Triola, 2003). A body mass index greater than or equal to the 95th percentile in comparison to children the same age and gender was the criteria used for...

According to Bennett, Briggs, and Triola, (2009), “analysis of variance (ANOVA), a method of testing the equality of three or more population means by analyzing sample variances” (p. 430)...

Patient and family satisfaction is the main descriptive statistics used when I observed the nurse at the local hospice office. After all customer...

The study that I have chosen will reflect statistical test used and what conclusions came about. We will also find out whether the findings...
