What are concrete populations?
For one each of your concrete and your hypothetical populations, give an example of a probability question and an example of an inferential statistics question. A population which is well defined and measurable is called a concrete population.
What is the difference between the concrete and the hypothetical?
Concrete operations are carried out on things whereas formal operations are carried out on ideas. The individual can think about hypothetical and abstract concepts they have yet to experience.
What is a hypothetical population example?
Hypothetical Population A population consists of sets of observations, objects etc that are all something in common. In some situations, the populations are only hypothetical. Examples are an outcome of rolling the dice, the outcome of tossing a coin.
What is a hypothetical population?
The population in which whose unit is not available in solid form is known as the hypothetical population. A population consists of sets of observations, objects etc that are all something in common. In some situations, the populations are only hypothetical.
What is sampled population?
-1. The target population of a survey is the population you wish to study. The sampled population is the population which you are able to observe in a sample. In an ideal world the target population and the sampled population would be the same, but often they are different.
What is a concrete operational thinker?
According to Piaget, thinking in this stage is characterized by logical operations, such as conservation, reversibility or classification, allowing logical reasoning. These mental acts cannot be applied in hypothetical situations and are still limited to concrete situations.
What does Jean Piaget believe?
Essentially, Piaget believed that humans create their own understanding of the world. In theological terms, he was a psychological constructivist, believing that learning is caused by the blend of two processes: assimilation and accommodation.
What are the two types of inferential statistics?
Since in most cases you don’t know the real population parameter, you can use inferential statistics to estimate these parameters in a way that takes sampling error into account. There are two important types of estimates you can make about the population: point estimates and interval estimates.
What is target population and sample 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”.
