1. Interpretation During today’s evaluation, we used the Preschool Language Scale- Fifth Edition (PLS-5) and general observations of the way Z plays and interacts with others to assess her speech and language skills. The PLS-5 is a norm-referenced test, meaning that the creators of the test developed a set of “typical” or “average” scores based on a large sample of children, to help clinician’s determine whether a child, like Z, performs at the same level as other children her age that were included

Ball 1 Missouri Counties Introduction: Does the size of a county’s population have any correlation to the number of individuals that are incarcerated within that county? Every year data is collected through the Annual Survey of Jails (AJS) that provides information on the characteristics and make-up of the Nation’s jails and inmates housed in these jails. The Offender Profile is another method of collection for the state of Missouri, reporting important statistics about the offenders supervised

Causal relationship It is a relationship between two variables where a change in one variable causes a consequence in the other variable (Cameron and Price, 2009:xvi). Causality Finding casual connections between two or more variables rather than just forming relationships between the variables (Bryman and Bell, 2003:367). Central Tendency According to Black (2010:61), the central tendency can be defined as the tendency for values in the data set being analysed, to be gathered around the middle

Adel Muhi CEN150 Assignment 1 Problem 1.3) I have taken a part so many devices for the purpose of learning. Some of the devices I was able to put back others failed. One of these failures devices was HDD (Hard Disk Drive). HDD is the most delicate device in the computer. I took carefully the HDD drive apart to see and learning how does it work and function. But as careful I was the device still failed because the device was too delicate the smallest mistake will brake some of the parts and

Do you prefer Kaldi’s or Starbucks? This choice is given to SIUE students every day. Our group chose to conduct an experiment that proves that students prefer Starbucks to Kaldi’s. To ensure we got the best results, we created an eight-question survey, which we used as factors in our descriptive statistics and regression outputs. They included: how old are you, what school are you in, what gender are you, do you prefer Starbucks or Kaldi’s, do you enjoy a treat with your drink, do you prefer a store

Research Design Essay: Evaluation of the Design of an Experiment The ability to describe and critically assess a design of any research trial can be beneficial in many various aspects. Firstly, it can assist in maintaining current knowledge through reading other empirical researches, developing critical and analytical thinking skills and to practice the research process in order to carry out further studies (Christensen et al., 2014). In the current trial, similar techniques will be employed to

strong assumption in general because it is very difficult to find and control all possible confounding variables. However, with a practical point of view, the conditional independence (or unconfoundedness) is stronger than the assumption used in statistical software. It means that the treatment does not influence on the conditional mean of each potential outcomes after controlling the covariates. In this study, it is possible to show that general firm characteristics are similar between the treatment

Materials Provided/Needed: Examiner’s Manual, Picture Book, Profile/Examiner Record Booklets, Student Worksheets, Manipulatives, Assessment Probes & Instructional Activities Book. Examiner and student will both need a pen or pencil. c. Alternate Forms: The TEMA-3 has two equivalent forms (A and B). III. ADMINISTRATION: a. Age Ranges: The TEMA-3 was designed for children ages 3-0 to 8-11. It can also

Chapter 1. 6. Many drug safety research studies are sponsored by pharmaceutical companies that would financially benefit if the results of the study are favorable. Is this an example of a potential confounding factor? If the sample to test is selected to favor the results of the drug company, it would be categorized as a confounding factor, but if instead the drug company is sponsoring a serious study where the sample is selected randomly and divided in treatment and control groups, the experiment

The Effect of the Size of a Superworm Introduction: For this experiment we were given superworms to experiment on. It was up to use students to decide what experiment we were going to perform on the worms. My group and I decided that we were going to observe how the size of the worms would affect how they reacted towards natural objects such as: sticks, rocks, leaves, mulch, and a pinecone vs an artificial object such as a straw. While doing this experiment, we observed the independent variable,
