What is experimental variation?
Experimental variation refers to the differences in outcomes or results that are observed between different trials or groups within an experiment. These variations can arise due to factors such as measurement errors, environmental conditions, or random chance. Minimizing experimental variation is important to ensure the reliability and validity of the experimental results.
What do you call a competition between two groups?
A competition between two groups is commonly known as a "match" or a "contest." This term is typically used in team sports or other competitive activities where two teams or groups compete against each other to determine a winner.
Classification by gender means giving separate treatment to .?
Men and Women
Why are there differences in observations between groups?
Differences in observations between groups can happen due to various factors such as differences in background characteristics, sample size, measurement tools, or random variation. These differences may occur because groups may have distinct experiences, exposures, or responses to the variables being measured, leading to variations in the observations. It is essential to carefully consider these factors when interpreting and comparing observations between different groups.
What is the difference between phosphorylase and phosphatase in terms of their functions and mechanisms of action?
Phosphorylase and phosphatase are enzymes involved in regulating cellular processes by adding or removing phosphate groups from molecules. Phosphorylase adds phosphate groups to molecules, while phosphatase removes phosphate groups. This difference in function affects how these enzymes interact with other molecules and influence cellular activities.
Why are there generation gaps between age groups cultural groups and gender?
DIVERSITY.
Why is sex a word?
It is a word used to describe the activities associated with procreation (intercourse)or as a means of defining gender groups. (Male and Female).
An experiment has a single factor with five groups ad seven values in each group What are the degrees of freedom?
In an experiment with a single factor and five groups, the degrees of freedom for the between-group variation is calculated as the number of groups minus one. Therefore, for five groups, the degrees of freedom is 5 - 1 = 4. Additionally, for the within-group variation, the degrees of freedom is calculated as the total number of observations minus the number of groups, which is (5 groups × 7 values) - 5 = 30. Thus, the degrees of freedom for the overall experiment would be 4 (between groups) and 30 (within groups).

Do Gazelle live in groups?
Yes, Gazelles do live in groups. These groups can sometimes be split by gender, usually so males can check for predators on their territory.

What are the sources of genetic variation in plants and each of the major pathogen groups?
mutation
What are three groups that influence gender roles?
whales birds and me ;)
How is it possible for one group to score higher than the other group and yet we conclude there is no reliable difference between the groups?
Given any two groups there will usually be random variations in their scores. A proper statistical test is designed to assess whether the observed difference is likely to be a result of such random variation or if it due to a genuine - reliable - difference between the groups.
A Population is made up of groups that have wide variations within the groups and less variations from group to group Which is the appropriate type of sampling method?
The question appears to have some confusion. The groups within a populations are not always fixed. A population may be divided in different groups in several alternate ways. It is for the researcher to decide if there is a need to identify these groups separately, and if so, what criteria is to be used for grouping. However, assuming that there is a need to divide the population in groups, it should be done in such a way that the variation within the group is minimized while that between the group may be high. The question assumes the reverse regarding variation within and between the group. Having clarified this issue, I will get down to answering the question of appropriate method of sampling for different groups within a population. There are two basic method of sampling - random and systematic. What method is appropriate in a given situation is not really dependent on the nature of groups within a population. Only requirement is that the method should be common for all the groups within the population. Another aspect of sample selection whether the total sample is to be drawn from the complete population without differentiating between group, or to draw sample from each group separately. The First method is appropriate when differences between the groups is not high, or when it is not necessary to analyse data group wise. It is best to draw sample form each group separately when, it is important to to do detailed analysis of each group separately, or when there is high variation between groups. When this is the selected method, then the additional question of sample size for each group need to be answered. There are three possible methods for this. First alternative is to take equal number of samples from each group. This method is appropriate when the size of each group is large and variation within groups is comparable, and sample size is decided based on desired level of accuracy and confidence. Second method is to decide sample size separately for each group based on variation within each group - higher the variation, larger the group. This method is appropriate when the variation within groups differ from group to group. Third method is to have have sample size proportional to the group size. This method is appropriate when size of each group is not very large and variations within groups is not is comparable for different groups.
ARE Human blood groups are an example of a trait that shows continuous variation.?
No, human blood groups are not an example of a trait that shows continuous variation. Instead, blood groups (such as A, B, AB, and O) are classified as discrete categories determined by specific alleles. Continuous variation typically refers to traits like height or skin color, which exhibit a range of phenotypes rather than distinct categories.
What type of interest group is the AFL-CIO and what is its purpose?
The AFL - CIO is an alliance of labor unions, which is the largest of these groups. It promotes ethnic groups, age groups, religious groups, or gender groups.
