After three weeks, the plants in group 1 showed much more growth than those in group 2. based on the results of this experiment, which is the best conclusion? they are valid because the student ran a controlled experiment. they are not valid because the student did not control all the variables that can affect plant growth. they are valid because the dependent variable caused a change in the independent variable. they are not valid because the time frame to grow a plant is too short.

From the above experiment conducted the best conclusion is that They are not valid because the student did not control all the variables that can affect plant growth.

Several variables, including seed type, water content, soil type, amount of light, temperature, and humidity, have an impact on plant growth.

A factorial experiment includes the study of plant growth.

A factorial experiment has a response variable, numerous factors (seed, water) that are set at various levels (plant height). The experiment's goal is to determine how various combinations of seed and water levels affect plant height. We can test the null hypothesis that seed and water have no effect on plants using analysis of variance.

Thus the experiment conducted will not be valid.
