What type of reasoning was used in the development of evolutionary theory

Inductive reasoning was used in the development of evolutionary theory.

What should be included in an experimental design because of the way data is analyzed using statistics

Replication should be included in an experimental design because of the way data is analyzed using statistics.

What is the only thing that should differ between experimental treatments

independent variable

Which tool is used by scientists to create models analyze data and show results

computer

What is a statement of no difference in experimental treatments

null hypothesis ^^^^right answer for A ls

What serves as a standard of comparison to evaluate the effect of the independent variable on the dependent variable

There cannot be one since the answer depends on the form in which the effect is measured: whether the effect is qualitative or quantitative.

There are various non-parametric measures of correlation or concordance. For data that are more quantitative there are more powerful tests such as the F-test for independent Normal distributions.

What type of information is being presented by a scientist who has a reason for presenting information a certain way

Biased

What is measured or tested by the data collected in a experiment

There are many different things that are measured and tested by the data collected in an experiment. Color changes are one thing that can be measured and tested for example.

What serves as a standard of comparison to evaluate the effectof the independent variable on the dependent variable
