Social change bring two types of changes one is positive change, which helps human life. Other type is negative in direction for which man show his resistance.
two advantage of atmospheric pressure are:
it is used in the to inject medicine in patient body atmospheric pressure is applied on syringe
it is also used to pump air in wheels of bicycle as atmospheric pressure is applied
According to me, no animal would be able to survive in a condition where the sunlight is blocked. As the sunlight is blocked, plants will not be able to make their food as they need sunlight for the process of photosynthesis. As the plants will not get enough nutrition due lack of food, they would eventually die. By this, the herbivorous animals which feed on plants, would not get their food . Also, the the carnivorous animals which depend on the herbivorous animals for food, would not be able to satisfy their hunger as the animals they feed on would be weak or maybe even dead.
the answer is deginlty true
Answer:
Using convenience samples to develop constructs and scales can be risky.
Explanation:
Convenience sampling refers to the process of gathering information from a sample that is conveniently available to the researcher (family members, friends in social media). This is not a random sampling method because not all of the members have the same probability to be selected.
- Using convenience samples to develop constructs and scales can be risky.
From the definition, we can say that using convenience samples to develop constructs and scales can be risky since <u>the information gathered by using this sampling does not necessarily represent the characteristics of the population (since it was not chosen at random).</u>
- It is a time-consuming process when there are a large number of respondents.
This is not a time-consuming process but is actually easier to gather information this way rather than by other methods.
- It is commonly used in the later stages of research.
This process is a gathering of information process and it takes place at early stages of the research
- The representativeness of the sample can be measured because sampling error estimates are not calculated
As we said before, this is not a random sample and therefore it is not necessarily a representative sample.
- It is commonly used to generalize results to the target population.
Although probably our sample shares some characteristics with our target population, this sampling is not used to generalize results to the target population.
