What two features must a sample have to accurately represent a population?

sample statistic
Sample data, if the experiment only captures a portion of the total population and population data, if the experiment captures the entire population.
The modal chromosome number is the most common chromosome number within a population or sample.
No. The standard plate count method is an indirect measurement of cell density of only viable bacterial cells. Optical density counting measure entire bacterial sample, the living as well as the dead bacterial cells.
The sample must be large and random.
differences between quantitative and qualitative data
You are studying the sample because you want to find out information about the whole population. If the sample you have drawn from the population does not represent the population, you will find out about the sample but will not find out about the population.
The statistics of the population aren't supposed to depend on the sample size. If they do, that just means that at least one of the samples doesn't accurately represent the population. Maybe both.
A sample that accurately reflects the characteristics of the population as a whole
sample
Biased sample
No. Only a census can ACCURATELY predict the outcomes: a random sample cannot.
at random to represent the population
A biased sample is a sample that is not random. A biased sample will skew the research because the sample does not represent the population.
