Dependent Variables In Quantitative Research

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 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

Variables: In this experiment, the temperature (in degrees Celsius) of the chemicals is the independent variable. To change the temperature, the materials are placed in a bath of water being heated by a hotplate.

Dependent variables are ones that change due to the independent variable. Independent variables are variables that can be manipulated or measured. This influences the dependent variables.

The dependent variable is observed to see how it changes in response to the experimental variable.

Determine which level of measurement— nominal, ordinal, interval, or ratio—is used in the following examples.

Independent variableIdentify the independent variable (IV), which is the variable that you hypothesize will cause or influence the other variable. *

C. The researchers analyzed the data as though it were at the interval/ratio level since they calculated means (the measure of central tendency that is appropriate only for interval/ratio level data) and standard deviations (the measure of dispersion for interval/ratio data) to describe their study variables.

Typically there are four different levels of measurements for variables. These are nominal, ordinal, interval and ratio. Nominal measurement is a numerical value. An example in the High School Longitudinal Study database used are the year’s math teacher has taught high school math. Ordinal measurement are the features that can be categorized. An example of this would be if you’re ranked the highest education of the parents. An ranking example is reflected below chart

The population that was used were individuals that were sixty-five years of age or older. These individuals were described to display restlessness, call-out, and physical aggression as their behavior. When conducting the study, the method and procedure of that were executed was the staff doing a five-day assessment of the individuals’ behavior to identify their responsive behaviors and documenting it. Then the families were asked to complete assessment to know more about the individuals’ history, likes, dislikes to better judge which item from the therapeutic activity kit was right for the individuals. And the facility had a list of items that they had and kept a record of the amount of each item that came and went. If the individual was not interested in an item, they were shown the item later. Duration of this Therapeutic Activity Kit (TAK) was for two weeks daily for the therapy and two weeks for the behavior

The independent variables are those that are changed throughout the experiment. In my experiment I am going to change the amount of egg white mixture on the ice cream (in my first experiment I put very little and the experiment didn’t work out). I will also be changing the type of ice cream. This will not affect the experiment but it will change the taste.

Nominal data does not have an inherent order. Dichotomous data is a type of nominal data which have one or two levels only. Ordinal data is made up of variables categories with undefined intervals based on an inherent order. Interval data can be continuous or discrete and is made up of an inherent order with equal intervals. For continuous data, any value in a continuum is used irrespective of the manner of reporting. Discrete data uses specific values which are expressed as counts (Fletcher et al., 2012).

This experiment was conducted to show what type of flour raises a cake the highest. I predicted that if you compare all-purpose, organic, and bread flour then organic flour will raise the highest because of the amount of protein in organic flour. The independent variable in this experiment would be the flour, it is what is changing in the experiment. Therefore, the cake is the dependent variable, the variable that I measured in the experiment. Things I made sure did not change was everything except the flour, that’s important because every ingredient has a key thing the help the cake, whether it’s cinnamon or sugar or vanilla, it’s all important. Important materials in this experiment is all-purpose, organic, and bread flour, cake recipe,

The number of young adults living at home has consistently increased since the recession, despite a seemingly improving economy (Shah, 2013). According to Lisa Wade, an associate professor at Occidental College in Los Angeles, CA, approximately 17% of young adults amid the ages of 25 and 44 still live at home (Wade, 2013). There are several unrelated issues that contribute to this staggering number. When trying to live out on your own; there is much to consider. If you begin living alone, at that point all the bills would be solely your responsibility. However, having a roommate or two would distribute the financial obligation and can be very helpful. This can also invade on the level of privacy that can be accumulated from living singly.

A variable is referred to as any event, situation, behavior, or individual characteristic that changes or varies. Any variable
