The Blood Sucking Behavior of Hirudo Miguel Soto Professor Folkerts Pepperdine University 23 April 2014   Abstract Hirudo are well known for their blood sucking, fluid feeding behavior. The purpose of this experiment was to get a better understanding of Hirudo’s blood feeding behavior; more specifically, the study was designed to answer the question: how do different volumes of blood affect Hirudo’s thirst? By soaking a sponge with different volumes of cow blood and measuring the time it took for

Introduction Animals can be conditioned to display or not display a variety of behaviors and emotions, including taste preference. This form of conditioning has even been successfully done in humans by using rotation-induced motion sickness after consuming either a familiar or unfamiliar flavored beverage to create a distaste for the beverage (especially the unfamiliar flavored one) (Arwas, Rolnick, & Lubow, 1989). A very common way to teach rats to dislike a certain taste is to give them injection(s)

The utilization of t-test, ANOVA, and comparing group means are essential in social research. When the researcher uses a test, the goal is to compare the averages of the two groups in order to determine if the sample population has shown any differences in the variables studied. Comparing group means through t-test and ANOVA is needed in social research as its goal is to produce results from the sample that can be generalized to the the population. In this paper will discuss what the author of

nursing. For this research paper, the focus is on the nonparametric test, T-test, and correlation. So, before I proceed, let me provide the definition of these test. “Nonparametric tests are sometimes called distribution-free tests because they are based on fewer assumptions (e.g., they do not assume that the outcome is approximately normally distributed)”. (,"Boston University School of Public Health " 2016, p. 1). The t-test is “a parametric statistical test for comparison of the means of two

More over the second hypothesis was that the mean difference in depression for men differed from the mean difference in depression for women because according to Silverstein et al. (2013), women were 33% more likely than men to have pure depression and over 50% more likely to have somatic depression. Finally, the third and last hypothesis was that the mean difference in self-esteem for men differed from the mean difference in self-esteem for women because according to Sprecher, Brooks, and Avogo

1 Chapter 7 Comparing Means in SPSS (t-Tests) This section covers procedures for testing the differences between two means using the SPSS Compare Means analyses. Specifically, we demonstrate procedures for running Dependent-Sample (or One-Sample) t-tests, Independent-Sample t-tests, Difference-Sample (or Matched- or Paired-Sample) t-tests. Unfortunately, SPSS does not provide procedures for running Z-tests. For the following examples, we have created a data set based on cartoon 9.1 (Cow Poetry)

ratio and that the population distribution of scores is symmetrical. Study Design: Independent variable: managers and employees Variable (Dependent): managers and employees reduced stress levels (aromatherapy) The type of t-Test is level to the variance, the independent t-test two groups are discrete and is exclusive due to the number (15) in each group, and the variance of the two groups is equal. Two types of errors: 1. Are there a significant difference between managers and employees using

Emotional Intelligence (EI) has been one of the popular concepts nowadays. However, the EI conceptualization varied between researchers, resulting in distinct types of EI theory proposed. These theories differ in the conceptualization of EI and its measurement instrument. The ability theory proposed by Mayer and Salovey (1997) suggests that EI consists of the ability to appraise and express, regulate and utilize emotion. It proposed four constructs that characterize all the abilities that could

The aim of this experiment was to basically analyze how fast the brain can perceive color and describe words simultaneously with the Stroop Effect theory. The Stroop Test is also done to determine new findings on the human’s brain automaticity and how it processes certain functions. In reference, to the independent and dependent variables involved, the independent variable in this experiment would be the color word followed by the conflicting color and the dependent would be the time that it took
