How is a sample is termed if it has similar characteristics to the population being studied.?
what is the type of sample in which each member of the sample set or group has an equal chance of being chosen

What is absolute sample size?
It is the number of elements in the sample. By contrast, the relative sample size is the absolute sample size divided by the population size.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
What is the difference between sample size and sample unit?
sample size is the specific size of a thing like the how long or wide. while sample unit is the whole thing not referring to specific number size.
Why should the sample size of the control group be the same as the size of the experimental group?
In a scientific experiment, the control group and the experimental group are treated the same way except for the variable being tested. Because the margins of error increase as the sample size gets smaller, both groups should be the same size.
The type of sample in which each member of the sample set or group has an equal chance of being chosen?
Random Sample
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.
When taking a systematic random sample of size n every group of size n from the population has the same chance of being selected?
No, that would be a random sample.
When taking a systematic random sample of size n every group of size n from the population has the same chance of being selected.?
No, that would be a random sample.
What is the type of sample in which each member of the sample set or group has an equal chance of being chosen?
biased
What are the differences between probability sampling and non probability sampling?
In a probability sample, each unit has the same probability of being included in the sample. Equivalently, given a sample size, each sample of that size from the population has the same probability of being selected. This is not true for non-probability sampling.

When taking a systematic random sample of size and n every group of size n from the population has the same chance of being selected?
That is not true. It is true for a simple random sample but not one that is systematic.
