Scientific Method Essays

The general investigative purpose of a psychology study (why the researcher has decided to conduct an investigation) is called its aim. A hypothesis is a precise and testable statement of what the researcher predicts will be the outcome of the study. In an experiment this is called the experimental hypothesis. In a correlational study the […]

Research methods, also called research designs, are the various ways that researchers employ in order to gather, organize, analyze and interpret data. Research methods depend heavily on the type of research being undertaken. There are three major types of research methods; developmental, experimental and evaluation research. Each has a number of distinguishing characteristics that make […]

For a researcher, it is of utmost importance to have adequate knowledge of the various research methods available. Gathering information has become important especially in relation to works of research. It is also important to be knowledgeable of these research methods to maximize their potential for acquiring information. There are various research methods to collect […]

This chapter includes the theories and methodological analysiss that have used throughout this research survey. This subdivision includes the theories that were used under the Survey procedure, Trials of associations and Advanced analysis. Survey Process Under this subdivision, the theories that have used in the study procedure are included. Sampling technique – Stratified random trying […]

Executing research necessitates a variety of decisions, including the choice of method, structuring the investigation, pondering aspects related to the plan, enhancing reliability and validity through measurement and optimization, picking participants, handling relations between investigator and participant, tackling researcher impacts, data analysis and ethical deliberations. When investigating if high noise levels interfere with memory task […]

The two important research methods are experimental and correlational. Many researchers use both methods to find outcome of their research. They may explore different avenues of an approach to gain the results they want. We will be describing the two methods and finding out which one is best. The definition of the experimental method is […]

Abstract This case study is dealing with research and different ways of tracking customers’ satisfaction as well as customer insight. What decisions has Enterprise made with regard to primary data collection-research approach, contact methods, sampling plan and research instruments? Enterprise made a decision to use a survey approach of its customers. Enterprise wants to know […]

Introduction The objective of this study survey was to assess whether there is a correlation between the role of school leaders and the motivation of instructors in a specific private secondary school. This section presents an outline of the methods used in the survey, which include: research context population and sample, research design and approach, […]

In industrial organizations there was a growing need to reduce absenteeism and increase performance with the marginal worker in order to have a more productive day.In this paper a marginal worker is defined as an individual who has failed to demonstrate consistent work attendance and or/has failed to meet organizationally defined standards of adequate performance […]

This lab report is about the conductivity of ionic solutions. In class we have been discussing wether all ionic solutions conduct equally well. If an solvent solution conducts electricity, then it must contain ions. So measuring the conductance of solutions can tell you whether the solutes in the solution are dissociated into ions. (Conductivity) Any […]

This activity uses the resonance of a column of air to measure the velocity of sound. English Activity: Setup i Equipment Glass Resonance Tube (Uniform Inside Diameter, With Scale Markings) Rubber Tube Reservoir Stand Low Frequency Generator (or Tuning Fork) Audio Measurement Setup (EA-200, graphic scientific calculator, data communication cable) Temperature Measurement Setup (EA-200, graphic […]

The laboratory’s goal is to resolve an issue or ascertain an answer to a question. It is suggested to formulate the hypothesis before starting with the tests. This will necessitate making educated assumptions about Experiment 1, which examines the approach that generates the least percentage error in density determination and its reasoning; as well as […]

The quality of water depends on several factors including oxygen-demanding wastes, disease-causing pathogens, microorganisms affecting health, plant nutrients, suspended solids and dissolved minerals. Other pollutants may be excess acidity due to acid rain, thermal pollution and substances such as benzene, chromium and mercury that are all toxic to aquatic life. As humans and land animals […]

ABSTRACT Pill bugs live in an outside environment where they are able to get the necessary amount of energy from organic matter. This environment is where water and organic matter is plentiful. In there natural habitat, pill bugs are found in dark, damp places. Living in moist places is important for pill bugs so they […]

There are many influences on the developing child which originate from the outside the immediate family structure (Murray, 1985). One of these influences is television. Since the 1960’s there has been much debate focusing on the impact of violence on television on the aggressive behaviour in children. It will be shown in this essay that […]

Physics Practical Report Experiment Ohmic Resistance and Ohm’s Law Aim To find out how current, voltage and resistance in a circuit are related, also to discover the relationship known as ‘Ohm’s Law’. Hypothesis In this experiment, conductors are used. Conductors which obey Ohm’s Law are called Ohmic conductors. Thus, for an ohmic conductor, a graph […]

Animal testing is the act of using non-human animals for scientific experimentation, usually to ensure whether a product is safe for humans or not. However, animal testing is used worldwide, and its purpose ranges from guaranteeing the safety of domestic products to aiding medical research, particularly in the areas of biology and chemistry. This has […]

Although we had a hypothesis about potato osmosis, the data we collected did not support the traditional definition of this process. According to convention, osmosis involves water moving through a semi-permeable membrane from an area with low solute concentration to one with high solute concentration. However, our results did not match this explanation. We expected […]

As human beings, we have set rules engrained into our minds called customs. Many of these vary from culture to culture but some are quite universal. One of those very universal rules, though the degree still varies, is the idea of personal space. In America, we have a strong sense of personal space, especially when […]

The Size of an atom LAB Introduction: In this particular experiment we are to measure the properties of certain substances using methods that cannot be done with standard measurement tools, such as a ruler, scale, or clock. For instance to find the size of the molecule of oleic acid we shall use an indirect method. […]

How high is the water conductivity level of the water sources in Goa Gajah? I predict the level of electrical conductivity of the water sources in Goa Gajah will be between the range of a normal drinking water, which is 0. 0005 to 0. 005 s/m. This hypothesis is based on the fact that conductivity […]
