* Z score = x -ms * The Independent part is what you, the experimenter, changes or enacts in order to do your experiment. The dependent variable is what changes when the independent variable changes - the dependent variable depends on the outcome of the independent variable.
4. There are several parts to the experiment such as both the independent and dependent variables. The independent variable is controlled or changed during the experiment to test the effects on the dependent variable. The dependent variable is tested and measured during the test .A controlled variable is an example for an independent variable would be variable that is held constant throughout the experiment. An example is a theory that could extend a person’s life expectancy. The independent variable is the amount of vitamin given to the subject within the experiment. The dependent variable is the life span
In my experiment, I decided to look at how or if different liquids effect the growth of a tomato plant. The independent variables in this experiment were the liquids that the tomato plants were watered with. The dependent variables in this experiment were the speed that the plants grew
In our Penny Lab, we wanted to extend what we were told to do with experimental design. We’re doing this because we wanted to prove what he thought our hypothesis had been, and a hypothesis can not be true unless it can be tested. We investigated what variables made the Penny Lab easier, or harder. As a class we decided to investigate variables like, dropping the penny from the same height, and applying the same pressure to the penny for each drop. But first we had to know what variables were, and which variables we needed to use in the experiment. The variables were, the independent variable, dependent variable, the experimental group, and the control group. We investigated this to show how much water a penny could hold, but we introduced
3. Why are researchers concerned about the representativeness of the samples in their studies? a. They don't want to offend anyone. b. They hope to generalize the findings of their studies to populations of interest. c. Representative samples are usually large enough to ensure statistical significance. d. Scientific journals will not publish a study unless the sample is representative. Objective 1.6 Describe the experimental method, state its advantages and disadvantages, and distinguish between independent and dependent variables.
Research Methods in Sociology and Anthropology By Western Governors University Abstract Sociology and Anthropology rely upon investigational and research techniques. While some of these may be similar they also differ. Each discipline has its own philosophical justification for their method but any and all approaches to
Be specific here! (“My independent variable would be…; My dependent variable would be…). If I was doing this study, my hypothesis would be that “people, who receive an aversive stimulus every time they give an incorrect answer, will try harder to get the correct answer than those who do not receive anything”. My independent variables, which are the variables that researcher manipulates, would be the electric shocks and the emotional motivation; and my dependent variable, which is the variable that is tested and measured, would be the members’ results.
A. Bees probably have a sense of smell. B. Bees probably do not have a sense of smell. C. It is possible that bees identify different kinds of flowers by smell. D. It is possible that bees do not identify different kinds of flowers by smell. 3. The dependent variable is observed to see how it changes in response to the experimental variable.

In an experiment, there are variables that need to be controlled and observed. They are the independent and dependent variables and the control variables. The independent variable is the variable that you are testing. The dependent variable is what you observe for change. The control are the ones that stay the same. In the experiment “Will the growth of the plant be affected by the color of the light”, the plant that has the white light will be the control variable, while the plants that have different light colors will be the independent variable which is what is being tested. The dependent variable will be the growth of the plant since that is what you are measuring or
The research question, in this case, is “Are subjects less accurate in their hypnotic response reporting under more anonymous conditions” (Younger et al., 2005). Independent variables are the variables that stand alone, and it is not changed by the other variables one is measuring. On the other hand, dependent variable refers to the variable that changes because of variations in the independent variable. Therefore, the independent variable is less accurate subjects and anonymous conditions while the dependent variable is the hypotonic response reporting.
In laboratory experiments all variables are under the control of the researcher, the researcher will obtain their results from taking two groups which are identical. One group will be the control group and the other will be the experimental group. The researcher will then alter the independent variable in the experimental group to see if the variable that the researcher is investigating changes in any way when compared to the control group. If there is
The study that this researcher is doing is an experimental because there is an independent and dependent variable and also there is a controlled variable. An independent variable is when the variable does not depend on the other variable. A dependent variable is when the variable depends on the other variable. The study’s independent variable would be the people that received the “miracle drug” and the dependent variable that they are trying to find is where
An independent variable is a variable that is manipulated and whose effect is being studied. The independent variable in this demonstration is the choices that each group had to pick from for their answer. A dependent variable is what changed due to the manipulation of the independent variable. The dependent variable in this demonstration was how the choices that each group had chose, or more specifically, how many people showed that they understood conservation and how many people did not.
The scientific experiment is the cornerstone of modern science and technology. Many of our advancements, like the lightbulb and the widespread use of electricity, owe credit to a properly set up experiment. Successfully setting up a valid experiment requires three main parts, but must also have an emphasis
