Pearson's chi-square test Essays

Complete Name: Unit 4 Student Name: Beard, Matthew ********************************************************************************************************** 1. Describe Mendel's P, F1, and F2 generations in his experiments with pea plants. Student Answer: Mendel was a pioneer botanist, and some of his earlier works involved the study of the seed shape and traits. One of the first (Peter Daempfle, 2001) seed plants that Mendel dealt with was pea plants that he first noticed were always round

administration of the test, class-teachers of the selected schools were requested to mark each student selected from the class as Bully or Non-Bully. The teachers were well acquainted with their student’s behaviors (at least class-room behaviors) and with rating guides which was prepared beforehand. No student was evaluated by more than one teacher. Thus, classification of students by teachers was done by holistic rating in a qualitative fashion without any knowledge of students’ test scores. The situation

Student’s t-test (P=0.0016), it was observed that there is a statistically significant difference between males and females and mean CFSS-DS scored. It was observed that females showed the highest CFSS-DS scores, with a maximum score of 60. The mean CFSS-DS scores for patients of first visit and patient with past dental visits were 34.2 ± 10.9 and 27.7 ± 6.5 respectively. It has been observed that highly significant difference was seen between the two groups using the paired Student’s t-test (P<0.0001)

What is the Relationship Between the Amount of Money a Team is Able to Spend and Their Position in the English Premier League? Rationale For my mathematical exploration I decided to base it around the topic of sports. While looking for a topic, sport stood out to me, as it has been a passion of mine ever since I was younger. I have also never thought about the significance of mathematics in sport other than in player statistics. This led me on the question how much does money play a role in a team’s

Stress is a part of day-to-day living of every individual. The college students may experience stress in meeting the academic demands, people on the job, business men may suffer stress to reach office in time and to complete the projects on time and even the house hole ladies may experience stress in managing the home affairs and to look for the maid servant. The reasons for the stress differ from person to person. The stress people experience should not be necessarily treated as harmful. An optimum

while waiting to receive completed questionnaires. This allowed the researcher to observe the HCP’s levels of compliance with the IPC protocol. The data were processed and analyzed using SPSS version 18. Frequencies, cross tabulation, Pearson’s, chi-square test, ANOVA were used to analyze the data. A p-value of <0.05 was considered statistically

analysis. Records with any missing data will be excluded. To test convergent validity, between the FLS and UCLA loneliness scale researchers will examine the Pearson’s correlation coefficients (Andreassen, Torsheim, Brunborg, & Pallesen, 2012). A strong positive correlation of greater than 0.7 (Francis, 2013) between the two scales for each item will show high convergent validity (Andreassen, Torsheim, Brunborg, & Pallesen, 2012). To test discriminant validity, researchers will assess this through

Stuttering is a disorder affecting fluency of speech, through interruption of the flow of speech by certain obstacles; repetitions, prolongations, blocks, interjection and others, negative reaction of the speaker to these interruptions inform of avoidance and struggle, and negative reaction of the listener to these interruptions which cause variable degrees of dys-prosody with the resultant poor intelligibility of a speech ]1[. Although a variety of theories have been proposed to explain its etiology

participants’ demographics, ocular and occupational history. Ocular examination included ophthalmoscopy and visual acuity, refraction, cover tests. Diagnoses were made on the presence of a condition(s) in either or both eyes. The Statistical Package for Social Sciences (SPSS) version 20.0 was used to analyze data collected. Descriptive statistics and Pearson’s Chi Square test were employed. Results: Out of the 150 respondents, 85.3% were males and

Scores were also reversed when items were negatively worded. Internal consistency of items was tested using Cronbach’s alpha and correlations were explored using Pearson’s correlation. For this article items with a p value of less than 0.01 was considered to be significant rather than 0.05. Cronbach's alpha test was carried out in this research paper however, the results of the internal reliability testing was below the acceptable average of 0.5 for non-clinical research in three of

Research Proposal Practical Application Activities in Mathematics: Can students’ understanding of mathematics concepts improve if the curriculum is integrated with the content area subjects? By: Juan Bottia, Tiffany Rampey, Aaron O’Brien National Louis University ESR 505 - Graduate Research: Mixed Methods Instructor: Dr. Erika Burton October 12th, 2014 Purpose of Study The goal of this investigation is to study the impact of using practical application methods to teach mathematics

There have been lots of theories and characteristics that make a leader effective but no article and journal clearly defines the traits that make a leader effective. Research on leadership roles has clearly shown that there are substantial differences in the judgments of multiple raters about which leadership roles have greatest influence on effectiveness. Gandhi, Adolf Hitler, Nelson Mandela, Barrack Obama, what do these people have in common? Most individuals would consider these people to be some
