Answer:
1. What is the population?
All soybean fields in randomly selected states from which he collected soil samples
2. What is the sample?
All soil samples of soybean fields.
3. What is the variable of interest?
Amount of significant differences of the sulfur levels in fields with and without the disease.
4. How was the sample selected?
The sample was selected by using simple random sampling method.
5. What method was used to collect the data?
As he collected all soil samples to check the significant differences the sulfur levels in fields with and without the disease. To check sulfur level requires experiment, so he used experimental method to collect data.
6. Is the variable qualitative or quantitative?
The variable is quantitative.
7. Is the variable continuous or discrete?
the variable is continuous because sulfur level can take any value i.e. integer or decimal thus it is continuous
The variable is continuous because the sulfur level can take any value, either integer or decimal, making it a continuous variable.
What is a discrete or continuous variable?
A variable is a quantity that varies in value, while a discrete variable is one whose value may be calculated by counting.
1. The population
All soybean fields in randomly chosen states from which he gathered soil samples made up the population of the experiment.
2. The sample
The sample of all soil samples in the soybean fields is the samples of the experiment.
3. The variable of interest
The number of significant changes in sulfur levels between diseased and unaffected fields.
4. The sample selected
The sample is selected by using a simple random sampling method.
5. The method used to collect the data
He took all of the soil samples to see whether there were any significant changes in sulfur levels between the fields with and without the illness. He employed an experimental approach to collect data in order to verify the sulfur level.
6. Type of Variable, qualitative or quantitative
The variable is quantitative.
7. Type of variable, continuous or discrete
The variable is continuous because the sulfur level can take any value, either integer or decimal, making it a continuous variable.
