Following enlisted are the answers for the above mentioned question.
Explanation:
1. Population pyramids is graphical representation of data which enables oneself to distinguish and have a clear picture in minds about the ratio of population densities keeping any one parameter as constant. Population pyramids could be used to analyze data in many different scales on the basis of gender,age groups, race etc. Examples-having a record of no. of individuals in different age groups in India.
2. Generally, there are 3 types of population pyramid on the basis of shapes of the pyramid. Those are;
- Expansive
- Constrictive
- Stable
Siting an example of age-sex pyramids,
In case of the Expansive, population pyramids show that the populations that have a larger number of persons in young age groups. The shape obtained hence is usually with high fertility rates with lower death rates
Then comes, Constrictive population pyramids. These are named so since they are constricted at the bottom. They undue a low percent of young people as compared with other age groups. These type of pyramids show decreasing birth rates.
And at last, Stationary also called as stable population pyramids are the ones which depicts almost equal proportion of the population in each of the all age groups. There is not a decrease or increase in population; it is stable.
Answer:
Projective tests are a type of personality test that is designed to have a person react to ambiguous stimuli to potentially reveal hidden emotions that are projected onto the test. In the Rorschach Inkblot Test a person is shown a series of ten black and white cards and asked to report the first thing that comes to mind. The participant then says what came to mind and may project some emotions onto the inkblot that were previous unmentioned. The person administering the test then records aspects of their reactions like gestures and tone of voice. In a thematic apperception test or TAT a person is shown an ambiguous scene and asked to create a story around it. The person can then reveal emotions that they did not previous mention in the story by stating how the characters feel and how the story ends. In a projective test a lot is up for interpretation based on the individual and how they are feeling at that time making the test lack both reliability and validity because of no grading scale being set in stone and results being inconsistent.

For a marketing research study to have validity, it must actually measure what it sets out to measure.
Explanation:
When it comes to research, we need to make sure that the measures we are using are reliable and valid.
Reliability refers to consistency across time, items, and researchers. Validity refers to what degree the results of the research reflect what they are intended to reflect (if the research actually measures what it has set out to measure). There are three main types of validity:
- face validity - the extent to which the research actually measures what it's supposed to measure;
- content validity - the extent to which a measure represents all aspects of the researched phenomenon;
- criterion validity - whether the results of the research correlate with other variables they are expected to be correlated with and not correlated with variables they are not expected to be correlated with.

Answer:
You should not because this can cause a grease fire. Grease fires, unlike traditional fires, cannot be put out with water, which can increase the risk of the fire rapidly spreading.
