Choosing a Variable Before I begin the investigation, I must first decide which variable I should investigate. Variables can be divided into 2 major groups: dependant variables and independent variables. In measuring the behaviour of a trolley the dependant variable is speed. This is because the speed will change when other variables are changed. An independent variable is a variable which cannot be affected by other variables. There are many independent variables in measuring the
article, they use six dependent variables that in their estimation best represent environmental degradation. The six dependent variables are CO2 emissions per capita, NOx emissions per capita, water pollution, rate of deforestation, area of land that is forested, and severe land degradation. The independent variable, democracy, was measured in two ways. The first was a continuous measurement that measured the democracy as an index. The other way was as a simple dummy variable, where democracy was coded
Moisture Content on Wheat Grain Seed's Respiration Rate HYPOTHESIS: There will be a positive correlation between moisture content of wheat grains and their respiration rate. Therefore as the moisture content (independent variable) increases so will the respiration rate (dependent variable). The rationale behind the hypothesis came from studying photosynthesis in plants. During the light-dependent reactions of photosynthesis, the photolysis of water (H2O) occurs inside photosystem II. The products of
the tools and the strategy that they are implementing so that the firm can make changes if needed (What is the importance of data analysis?.n.d.) From time to time. The basic reason being, as the business environment has become very dynamic, it highly essential to keep the track of the environment and should understand the behavior of business movements,
Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. The first independent variable that will be tested. The tennis ball is the constant variable factor (the variable that is kept the same, to make the investigation valid). The ball will dropped from increasing heights (cm-25, 50, 75,100,125,150,175,200)
SugarsWe will test five different solutions for presence or absence of reducing sugars using a premixed Benedict's reagent. These dependent variable solutions will be water, glucose , onion juice, potato juice, and starch suspension. When the Benidict's reagent is combined with sugars at a boiling temperature, a color reaction will occur. Our independent variable, Benidict's reagent color is blue.The negative control will be the combination of water and Benidict's reagent. This sample will undergo
What are Variables that Influence your Classroom Community? This is a very complex and loaded question. An unlimited amount of variables will and do influence what goes on it your classroom, and not every single one of them has a fix or a solution to what causes the problem. Four variables that I will be looking at that influence a teacher’s classroom community are culture and poverty, the increasing difficulty of the standards, student and teacher relationships, and family dynamics. One of the
Circuit Task: To investigate how length and width of copper wire affect on the current of a circuit. Prediction: In this experiment, the input variable will be changing the length of the copper wire used in the experiment, and also the SWG of the wire, which means the width of the wire. By changing this variable, the current the circuit will vary. With my knowledge in science and some research on the factors that affect a circuit's resistance. I am able to
I am a part of the Southeastern conference of Seventh-day Adventist. This is an environmental analysis of this organization. The Macroeconomic variables which affect my organization as well as the internal variables which relate to these different macroeconomic variables will be discussed in this environmental analysis. External Macroeconomic Variables: How they affect the Church Societal Changes: Changing Member preference. Governmental Changes: New Legislation: Impacting what can and can’t

Investigating Rate of Reaction Aim I am going to investigate the rate of reaction between calcium carbonate and hydrochloric acid. I will look at the various factors affecting the reaction and select one variable to change, while the others keep constant in order to carry out a detailed investigation. Formulae
Claustrophobia Does Claustrophobia cause people to deviate from confined areas? The independent variable is claustrophobia, and the dependent variable is the confined areas. Our hypothesis to this question is yes claustrophobia can be cured and reduced by cognitive behavioral therapy. The issue of claustrophobia is very important due to its impact on an individuals everyday life, since it affects a number of individuals throughout the world. A phobia is an anxiety disorder that is shown by an irrational
are formed. Successful collisions (those with sufficient energy) can be increased (or decreased) by a number of factors. These key variables consist of temperature, concentration, surface area and use of and type of a catalyst. To examine the relationship between the rate of reaction and surface area I must choose to vary only surface area keeping the other variables constant. Surface area of solid - The surface area has an effect on the rate of reaction. If the solid has a large surface area per

Investigation looking At the Speed of Reactions Introduction The aim of this experiment is to find out how a variable can affect the results from a scenario set up in scientific environment. The experiment is to see how a certain variable will affect the amount of Gas produced from a Calcium Carbonate and Hydrochloric Acid Reaction. The Science Calcium Carbonate is a generally white or colourless mineral that is translucent. When compressed or exposed to great heat the mineral binds together
but less crucial. The important point, however, is that all decisions will have some sort of effect. Variables in Decision-making In some cases, decisions are made where there are few alternatives and all the parameters of the decision can be clearly identified. However, many decisions require that a choice be made between different courses of action that may be affected by variables or events beyond a manager's control. For example, the field director of a refugee relief operation knows
keep all variables the same except the one we area investigating. My variable that I am going to investigate is going to be the concentration of the sodium thiosulphate. Sodium thiosulphate solution and dilute hydrochloric acid produce a solid (seen as cloudiness). I am going to time how long it takes for the solid to block out a cross underneath a conical flask. From the time taken I can calculate the rate of reaction by working out 1/time (units s-1). Variables The variables that may
There’s More That Meets the Eye The dead speak to the living in various forms. Humans are gifted with experts who translate the clues of the deceased including psychics, medical examiners, forensic pathologists, and forensic anthropologists. Anthropologists study bones, pathologists examine the “cause and development of disease,” and merging into forensics skews their missions (“Career”). For instance, forensic anthropologists study any causes of death available in the bones and aid the identification

In order to compete in today’s changing environment, Airborne Express needs to move away from its old fashioned centralized structure and form a more decentralized structure. The old fashioned structure is not the only variable that makes Airborne the follower in the air express industry. The Internet and information systems are transforming the air express market into an electronic
a chance for market segmentation strategies. Market segmentation is the selection of groups of people who will be most receptive to a product. This is done using both Demographics (variables such as age, sex, race, income, occupation, education, household status, and geographical location); and Psychographics (variables such as activities, interests, opinions, product-use patterns, product benefits, and the topic of this research paper lifestyles). Life Styles are much more than just how a person
