Predictions from a sample of survey respondents are likely to be valid only when the sample is representative of the population as a whole. true or false

Answers

Answer 1

Answer:

Explanation:

A representative sample is a subset of a population that seeks to accurately reflect the characteristics of the larger group. For example, a classroom of 30 students with 15 males and 15 females could generate a representative sample that might include six students: three males and three females.

Answer 2

Answer:

True

Explanation:

Most survey researchers want to use results from a sample to make predictions about a population. For example, in the political candidate survey, researchers might want to predict how all voters feel about the candidate based on results from a sample of voters. Predictions from a sample are likely to be valid only when the sample is representative of the population as a whole (in this case, all voters).

Answers

Answer:

c. What is good for the environment is good for our health.

Explanation:

People's health largely relies on the environment they are living in. For example, people breathe in oxygen that comes from the plants. If plants will be well-nourished, they'll grow and become more abundant. This means that people will have more fresh air (oxygen) to breathe, which is essential for their health. This makes choice A and D incorrect because the environment clearly affects our health. Therefore, our collective health is related to the health of the environment.

When the environment is damaged, our health declines. This makes choice B incorrect. For example, if a forest is destroyed by wildfire, the plants and animals will also be gone. This means that people will have no more shade from the sun and food supply will become scanty.

Why are starfish radially symmetrical?
Sea stars, for example, have eyespots at the end of each of their arms, rather than in a "head" region. One advantage of radial symmetry is that it may make it easier for organisms to regenerate lost body parts.

How can you find your own heart rate? Is there a math equation that you could use? PLEASE HELP!!!!

Answers

Answer:

To find your heart rate, there are a lot of ways to do it but neck and wrist are the top two i'd say.

Neck: Take two fingers and place them in the more hollow part of your neck by your "adam's apple" (or larynx) in the middle (place them on any side but it might be easier on the right).

Wrist: To find your wrist pulse, you take two fingers again and put them on the same side of your wrist as your thumb, by the bone in the middle. If you don't know what I'm talking about there is a bone right in the middle of you arm (starts at the wrist pretty much) and to the same side of your wrist as your thumb, if you place your two fingers there you will find a pulse!

{The equation to find maximum heart rate is to take your age and subtract it from 220.}

BUT, to find the regular heart beat at that second all you have to do is count how many beats you have in 15 seconds and multiply that number of beats by 4 to know your beats per minute.

What are the limitations of correlational research?

Answers

Explanation:

Limitations of Correlations

Correlation is not and cannot be taken to imply causation. Even if there is a very strong association between two variables we cannot assume that one causes the other. For example suppose we found a positive correlation between watching violence on T.V. and violent behavior in adolescence.

An important limitation of correlational research designs is that they cannot be used to draw conclusions about the causal relationships among the measured variables. Consider, for instance, a researcher who has hypothesized that viewing violent behavior will cause increased aggressive play in children

Correlational study,  It's impossible to infer causes, and a high correlation between variables might be deceiving.

Correlational research approaches have the drawback of not being able to make conclusions regarding the causal links between the measured variables. Consider the hypothesis of a researcher who claims that youngsters would engage in more aggressive play if they are exposed to violent conduct.
