Are The Observations Independent?


Independent Observations

Two observations are independent if the occurrence of one observation provides no information about the occurrence of the other observation. A simple example is measuring the height of everyone in your sample at a single point in time. These should be unrelated observations.



What are dependent observations?

Dependent observations are observations that are somehow linked or clustered; they are observations that have a systematic relationship to each other. Clustering typically results from research and sampling design strategies, and the clustering can occur within space, across time, or both.


What is the difference between facts and assumptions?

The difference between a fact and an assumption may not be obvious. A fact is something that has occurred or is actually the case. The usual test for a statement of fact is verifiability; that is, whether it can be proven. An assumption, on the other hand, is a belief without proof.


What is the difference between an observation and a fact?

A fact is a statement that is verifiably true, while there is no way to completely verify this statement. An observation is a statement made based on something the viewer has seen or noticed, and that does not really apply here.


What is the difference between inference and hypothesis?

INFERENCE: Using background knowledge to make a guess about something you have observed. HYPOTHESIS: (Similar to a prediction) Using research and background knowledge to make a guess about something that has NOT yet happened.


What is an assumption based on observation?

A common assumption across all inferential tests is that the observations in your sample are independent from each other, meaning that the measurements for each sample subject are in no way influenced by or related to the measurements of other subjects.


What is meant by assumption in psychology?

n. 1. the premise or supposition that something is factual or true; that is, the act of taking something for granted. 2. one or more conditions that need to be met in order for a statistical procedure to be fully justified from a theoretical perspective.

Two observations are independent if the occurrence of one observation provides no information about the occurrence of the other observation. A simple example is measuring the height of everyone in your sample at a single point in time. These should be unrelated observations.


What is an example of a dependent sample?

For example, the following experiments use dependent samples: A training program assessment takes pretest and posttest scores from the same group of people. A paint durability study applies different types of paint to portions of the same wooden boards. All paint types on the same board are considered paired.


What are examples of observations?

A few other scientific observation examples include the following:

  • A scientist looking at a chemical reaction in an experiment.
  • A doctor watching a patient after administering an injection.
  • An astronomer looking at the night sky and recording data regarding the movement and brightness of the objects he sees.


Can assumptions be facts?

A fact is something you know is true and you can prove is true. An assumption is something you think is true, but you might be wrong, or you don't have enough evidence to prove it's true.


What is an assumption of this perspective?

An assumption is something that is accepted as true. A belief is when that assumption is proven to be true or just held with more conviction. A perspective is an attitude or point-of-view. In other words, an assumption is about an object. A perspective is the point-of-view in which you are seeing that object.
