A scientist wishes to test the effects of different amounts of water and fertilizer on yields of corn. In a series of experimental fields, she varies the supply of water and the amount of fertilizer applied to a given strain of corn and measures the yield of the crop that results. In this experiment, which is/are the dependent variable(s)?

• Corn yield and the variety of corn

• Corn yield

• Water supply

• Amount of fertilizer and variety of corn strain

In Biology, a scatter plot showing a downward trend indicates:

• A positive correlation

• A negative correlation

• No correlation

• A causal relationship

An r2 value of 0.958 shows...

• A positive strong correlation between variables.

• A negative strong correlation between variables.

• A positive weak correlation between variables.

• A negative weak correlation between variables.

a P value of 0.03 shows that...

• There's a statistically significant difference between the groups.

• There's not a statistically significant difference between the groups.

What is the result of a t-test in Biology?

• p value

• r2 value

• mean

• standard deviation

Standard error in Biology is primarily used to:

• Measure the accuracy of the sample mean as an estimate of the population mean + accuracy

• Calculate the mean of a dataset

• Determine the range of data points

• Establish causation between two variables
