Observation is the only option that is not a variable in scientific experiment.

<h3>What are variables in scientific experiment?</h3>

Variables are factors, or condition that can exist in differing amounts during a scientific experiment.

<h3>Types of variables in scientific experiment</h3>

Scientific experiment usually has three kinds of variables:

  • independent,
  • dependent, and
  • controlled.

Thus, Observation is the only option that is not a variable in scientific experiment.

The complete question is below:

Which of the following is not a type of variable in a scientific experiment? A. Independent B. Control C. Dependent D. Observation

Gala2k [10]
Lets consider the water drop as being part of the water in a lake. The water droplet evaporates and changes from a liquid state to a vapor state by gaining energy and travels up to the upper atmosphere. In the atmosphere the water droplet once again condenses in the clouds and is stored until it can be precipitated on to the land again in the form of rain or other forms of precipitation.

The students concluded that pea plants grew better in compost than did melon plants. Which of the following best addresses the v
musickatia [10]

Answer:

c. The conclusion is invalid because other variables in the experiment affected the results.

Explanation:

Consider the complete problem:

A group of students designed an experiment to determine the effect of compost on the germination and growth of plants.

The students set up experimental plots by mixing different ratios of soil and compost. They planted 20 pea and 20 melon

seeds in each plot and watered each plot regularly. The students recorded the number of seeds that germinated, and as the

plants grew they recorded the plant length, number and size of leaves, and general health observations.

The following observations were recorded.

 In all treatments, more pea seeds germinated than melon seeds

 There was a week of rainy weather at 3 weeks

 Melon plants developed a fungal growth at four weeks

 Melon plants grew longer than pea plants, but many melon leaves showed signs of yellowing as the weeks passed

The students concluded that pea plants grew better in compost than did melon plants. Which of the following best

addresses the validity of the conclusion made by the students?

a. The conclusion is valid because the independent and dependent variables in the experiment were controlled.

b. The conclusion is valid because the experimental design included a large sample size.

c. The conclusion is invalid because other variables in the experiment affected the results.

d. The conclusion is invalid because the units of measurement were not given in the experimental design.

<em>In order for the conclusion to be valid, all the independent variables should have been controlled. In this case, the independent variables such as the amount of water received by the plants, nutrient requirement of the plants, etc. were not controlled leading to fungal attack on the melon plant.</em>

<em>Hence, the conclusion is invalid because other variables that ought to have been controlled affected the experimental outcome.</em>

<em>The correct option is c.</em>
