What does it mean when a part of the population is under represented?
A part of the population is under-represented when it is proportionally smaller in its population than in a sample.
What is population dispersion quizlet?
Dispersion. – A property of populations, pattern of spacing of individuals within the area the population inhabits. Patterns include clumped, uniform, and random.
What do you call the part and representative group of a population?
Sampling is the process of selecting a representative group from the population under study. The target population is the total group of individuals from which the sample might be drawn. A sample is the group of people who take part in the investigation. The people who take part are referred to as “participants”.

Demographers (people who study human populations) categorize this as the natural population.
What is a frame in statistics?
Frame. The frame refers to the list of units (eg, persons, households, businesses, etc) in the survey population. Since the selection of the sample is directly based on this list, the frame is one of the most important tools in the design of a survey.

What is the difference between density and dispersion?
What is the difference between density and dispersion? The density of a population is the number of individuals per unit area or volume. Dispersion is the pattern of spacing among individuals within the boundaries of the population.
What are the 3 types of population distribution?
Individuals of a population can be distributed in one of three basic patterns: they can be more or less equally spaced apart (uniform dispersion), dispersed randomly with no predictable pattern (random dispersion), or clustered in groups (clumped dispersion).
What is a sample group?
In statistics, a sample group can be defined as a subset of a population. The population, or target population, is the total population about which information is required.
What is the part of the population being studied?
The whole group that is being studied. A sample in a research study is a relatively small number of individuals about whom information is obtained. The larger group to whom the information is then generalized is the population. A census is a survey which measures an entire population.
Is a portion of the population selected for study?
Sampling can be defined as the process through which individuals or sampling units are selected from the sample frame.
What is a subset of a sample?
The set of all the possible outcomes is called the sample space of the experiment and is usually denoted by S. Any subset E of the sample space S is called an event.
