cannot be determined
In the graph, was there any statistical significance between the control and treatment in any of the species?
yes between all three
none at all
yes but only in versicolor and virginica
yes but only setosa
Two ecosystems of the same classification were studied for the number of a particular species. It was found that one ecosystem 1 contained an average of 2.6 species and ecosystem 2 had 3.7 species. The p value was 0.06. Which ecosystem contained more of the species?
The p value shows that the data is significant therefore ecosystem 2 had more of the species
The p value shows that the data is significant therefore ecosystem 1 had more of the species
The p value shows that the data is not statistically significant therefore neither ecosystem had more of the species
The p value shows that the data is not statistically significant therefore ecosystem 2 had more species
Which of the following describes your ability to analyse and interpret data on excel using the data analaysis toolpak? I.e. can you generate descriptive statistics and perform a t test to find p value and then interpret what this means for the data
I have absolutely no idea what you're on about
I can do some but I get stuck
I am reasonably comfortable creating it but I can't explain what I did
I am confident that I can do all of that reasonably well
