How do scientist divide large groups into smaller groups?
Its a statistic, they guess. A good guess, but they still do.
What are independent and dependent variables in science?
Dependent variable is the variable that can be measured. However, the independent variable is the variable that changes in the two groups.
When independent sample t test is used?

What are the criteria for duncan's multiple range test in statistics?

How do you do grouped data?
You define groups by selecting non-overlapping subsets of the domain which, together, cover the whole domain. For each group you combine responses for all units whose domain element (explanatory or independent variable) falls within the group.
What is the primary advantage of a repeated-measures design over an independent-measures design?
The primary strengths of the repeated measures design is that it makes an experiment more efficient and helps keep the variability low. This helps to keep the validity of the results higher, while still allowing for smaller than usual subject groups. twas on wikipedia so not so reliable
Do bandicoots live in groups?
No. They are independent and do not live in groups.
Uses of ANOVA?
The ANOVA test means ANalysis of Varience and it is used to test for difference among group means. ---- That is the amount of variability between the means of the groups compared to the amount of variability among the individual scores of each group. Varience between groups versus varience within groups. Hope this helps...Natalie

What are the components needed in order for an experiment to be valid?
For an experiment to be valid, it needs a control group to compare results, random assignment of participants to groups to minimize bias, manipulation of an independent variable to observe its effect, and reliable measures to accurately record outcomes.
