What are the independent and dependent variables in the farmer’s experiment?
What are the independent (treatment) and dependent (response) variables in the farmer’s experiment? The independent variable is number of rows and the dependent variable is number of berries harvested
What was the conclusion of the farmer’s experiment?
The farmer’s experiment was widely considered to be well-designed and well-implemented. After 8 weeks, he found no difference between groups, and the berry harvest was still lower than in previous years. What can he conclude about his hypothesis? Rodents are eating the berries.
What is the independent variable in research?
Since the outcomes are totally dependent on the kind of treatment, the independent variable is the kind of treatment provided to the group, real or fake (placebo). Are you a student or a teacher?
What is the dependent variable in the tomato experiment?
All experiments have an independent variable (the different fertilizer types in this case) and a dependent variable (the number of tomatoes grown). Say you wanted to look at the impact of different types of fertilizers on your tomato plants. You want to grow the most tomatoes so that you can make a delicious marinara sauce for your friends.
What are the independent treatment and dependent response variable in the farmer's experiment?
What are the independent (treatment) and dependent (response) variables in the farmer's experiment? The independent variable is presence/absence of nets and the dependent variable is number of rows.
What is the independent variable treatment in the experiment?
The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
Is the treatment the independent variable?
The treatment is any independent variable manipulated by the experimenters, and its exact form depends on the type of research being performed. In a medical trial, it might be a new drug or therapy.
What is the independent test variable of the experiment?
An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable.
What is the independent and dependent variable in an experiment?
Independent variables (IV): These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable. Dependent variables (DV): These are the factor that you observe or measure.
Which is the independent variable?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

What is a treatment condition in an experiment?
In experimental design, a level of an independent variable or combination of levels of two or more independent variables. For example, in an experiment examining the effects of four different drugs on dreaming, research participants or subjects would receive a different drug in each treatment condition.
What is a treatment in experimental design?
In terms of the experiment, we need to define the following: Treatment: is what we want to compare in the experiment. It can consist of the levels of a single factor, a combination of levels of more than one factor, or of different quantities of an explanatory variable.
What are some examples of independent and dependent variables?
The type of soda – diet or regular – is the independent variable. The level of blood sugar that you measure is the dependent variable – it changes depending on the type of soda.
What is the dependent variable in an experiment?
The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is what is being measured.
What is the independent variable in an experiment quizlet?
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
What is an independent variable?
Independent variables are the variables that the experimenter changes to test their dependent variable. A change in the independent variable directly causes a change in the dependent variable. The effect on the dependent variable is measured and recorded. Common Misspellings: independant variable.
What are the two main variables in a science experiment?
The two main variables in a science experiment are the independent variable and the dependent variable. Here's the definition on independent variable and a look at how it's used:
What is the difference between independent and dependent variables?
When graphing data for an experiment, the independent variable is plotted on the x-axis, while the dependent variable is recorded on the y-axis. An easy way to keep the two variables straight is to use the acronym DRY MIX, which stands for:
What is the independent variable of a moth reaction?
The independent variable is the amount of light and the moth's reaction is the dependent variable . In a study to determine the effect of temperature on plant pigmentation, the independent variable (cause) is the temperature, while the amount of pigment or color is the dependent variable (the effect).
What is the variable that responds to the change in the independent variable?
The variable that responds to the change in the independent variable is called the dependent variable. It depends on the independent variable. The independent variable is graphed on the x-axis.
Does the scientist have control over the student test scores?
On the other hand, the scientist has no control on the students' test scores. The independent variable always changes in an experiment, even if there is just a control and an experimental group. The dependent variable may or may not change in response to the independent variable. In the example regarding sleep and student test scores, ...
What is the independent variable in an experiment?
The independent variable is: What the experimenters set up in advance to make two or more groups different from each other. (In the example, the two rooms were set up to show different movies.)
How to determine the independent variable?
The independent variable in an experiment will always be identified using three rules. The independent variable is: 1 What the experimenters set up in advance to make two or more groups different from each other. (In the example, the two rooms were set up to show different movies.) 2 Always what happens first before the outcome is measured. (People watched a movie first, then the amount of popcorn they ate was measured at the end, so the movie watched is the independent variable.) 3 Considered the cause of any changes in the dependent variable. (Different types of movies were considered the cause of any differences in amount of popcorn eaten. The amount of popcorn is considered dependent on which movie was watched.)
How do dependent variables work?
How Dependent Variables Work. The dependent variable can be identified based on the outcome of the experiment, or what is being measured. In our movie experiment, the researchers measured how much popcorn is being eaten. This means that the amount of popcorn eaten is the dependent variable.
What is the outcome of an experiment called?
Variables are criteria in an experiment that can be changed or measured. The outcome of an experiment, or what is being measured, is called the dependent variable. Whatever makes the two groups in an experiment different from each other is called the independent variable.
Is the variable x an independent variable?
1. Since the value of y is dependent on x, the change in the value of y is totally dependent on any change in the value of x. Furthermore, the value of x changes first before the value of y is affected by that change. Hence the variable x is the independent variable.
Is popcorn a dependent variable?
This means that the amount of popcorn eaten is the dependent variable. Let's look at a couple other examples. All experiments have an independent variable (the different fertilizer types in this case) and a dependent variable (the number of tomatoes grown).
Answer
The success of an experiment depends on a number of factors provided while experimenting like proper review of literature and proper information. The given question on soil ecology studies the effect of compost on the growth of several crops.
Answer
Significant mistakes during an experiment can be failing in defining experimental and control groups ( many different species and no control groups) and not keeping controlled variables constant.
