A guess about how something in science works.
A testable answer to scientific question.
None of these definitions describe what a hypothesis is
Imagine that you design and conduct an experiment based on your hypothesis that adding activated charcoal to soil allows more plants to grow. You find that in the soil with activated charcoal, more plants grew than in the soil without activated charcoal.
As a researcher, you would say that:
the results of your experiment do not support your hypothesis.
the results of your experiment support your hypothesis.
your results proved your hypothesis right.
your results proved your hypothesis wrong.
Predictions made from a hypothesis should include
Both an independent and dependent variables.
No variable at all.
Only dependent variable.
Only independent variable.
Many people describe hypothesis testing as counter intuitive because
we can only conclude that nothing happened when we are 100% sure that something did not happen.
we test whether nothing happened in order to conclude that something happened.
we test whether something happened but can still conclude that nothing happened.
d. we test whether
we test whether something happened in order to conclude that nothing happened.
A type I error occurs when we
correctly fail to reject a false null hypothesis.
correctly reject a false null hypothesis.
incorrectly reject a false null hypothesis.
incorrectly reject a true null hypothesis.
Null and alternative hypotheses are statements about:
population parameters.
sample parameters.
sample statistics.
it depends - sometimes population parameters and sometimes samples statistics.
A test to screen for a serious but curable disease is similar to hypothesis testing, with a null hypothesis of no disease, and an alternative hypothesis of disease. If the null hypothesis is rejected treatment will be given. Otherwise, it will not. Assuming the treatment does not have serious side effects, in this scenario, it is better to increase the probability of:
making a Type 1 error, providing treatment when it is not needed.
making a Type 1 error, not providing treatment when it is needed.
making a Type 2 error, providing treatment when it is not needed.
making a Type 2 error, not providing treatment when it is needed.
One problem with hypothesis testing is that a real effect may not be detected. This problem is most likely to occur when
the effect is small and the sample size is small.
the effect is large and the sample size is small.
the effect is small and the sample size is large.
the effect is large and the sample size is large.
In a hypothesis test:
the null hypothesis is what we are trying to prove
the alternate hypothesis is always assumed to be true
the alternate hypothesis is accepted unless there is sufficient evidence to say otherwise
the null hypothesis is not rejected unless there is sufficient evidence to reject it.
Which of the following is correct null hypotheses in line with the research question below:
“Is there significant relationship between the length of ear and life span?”

Why is correlational research used to test between two variables?
It is done to establish the effect of one on the other and how that affects the relationship.
It is used to survey or do a normative approach to study prevailing conditions.

Sampling
Sampling frame
Why probability sampling is the best type of sampling technique used in a research study?
There is higher complexity compared to non-probability sampling.
There is absence of systematic error and sampling bias.
It is very cost-and-time effective.
Which of the following is the type of probability sampling that uses a pure chance selection process?
Systematic sampling
Stratified sampling
Simple random sampling
Cluster sampling
What sampling technique is used when the researcher would like to consider giving equal chances to the members of the accessible population being selected as part of the study?
Systematic
Stratified
Simple Random
Cluster
When can we consider a research sample as the “best”?
Systematically chosen
Representative of the population
Purposely selected
Conveniently represented
What is the main objective of using stratified random sampling?
Sample is proportionately drawn from the different categories of the population.
Sample is taken from an accessible population than the target population.
Every individual will be given an equal chance to be selected.
Those who will possibly respond to treatment are chosen.
Why do we need to consider bigger number of respondents in research study?
Because it will make the research more challenging for the researcher.
Because research is time consuming and cost–efficient.
Because it will make the research process easier.
Because it will avoid sample errors.
