Question

Give an example of a directional hypothesis.

Answer #1

Directional hypothesis- The prediction made by the researcher in the context of the proposed study allied with the either positive or negative facets is termed as directional hypothesis.

Example 1- A lecture by a professor using Power bpoint presentation, images and visuals will be be remembered more by the participants/ aspirants/ students as compared to an extempore lecture/ one sided monotonous flow.

Example 2- If there's affection, affinity a bond between teacher and school children, they will be more involved in learning than a mere formal relationship between teacher and school children without affection.

Example of non directional two tailed hypothesis

Why is the peppered moth an excellent example of directional
selection?

Since obtaining statistical significance is easier to obtain
with a directional hypothesis (one-tailed test) than with a
non-directional hypothesis (two-tailed test), why would anyone ever
design a study with a nondirectional hypothesis?

___ non-directional test
___ directional test
___ alpha
level
___ null hypothesis
___ alternative
hypothesis e.
___ rejection range
___
inferential
___
inference
___ significance tests
___ statistical power
a. The hypothesis that is rejected or retained using inferential
statistics and is often the opposite of what the researcher
believes to be true.
b. The researcher hypothesizes that a given score will be either
higher or lower than the chosen level of significance.
c. The likelihood of rejecting the null hypothesis...

Provide an example of the following: (a) A research problem
appropriate for a non-directional test using the one-sample
z-statistic. (b) A research problem appropriate for a directional
test using the one-sample t-statistic.

What does the level of significance represent in a test of
hypothesis?
Please give 1 example and explain thoroughly

Below are five non directional hypotheses. Restate each one as a
directional
hypothesis.
1. Tactile stimulation is associated with comparable physiologic
arousal as
verbal stimulation among infants with congenital heart
disease.
2. The risk for hypoglycemia in term newborns is related to the
infant's birth
weight.
3. The use of isotonic sodium chloride solution before
endotracheal suctioning is related to oxygen saturation.
4. Fluid balance is related to degree of success in weaning
older adults from
mechanical ventilation.
5. Nurses...

Give an example of a problem where it would be appropriate to
use a statistical hypothesis test for the population mean. Explain
what you can determine with such test and how confident you are in
your conclusion.
