A PET scan would be most useful for detecting brain areas that are most active as a person performs mathematical calculations.
Transect sampling is a method used in ecological studies to assess the distribution and abundance of species within a specific area. It involves laying out a predetermined line or path, called a transect, across a habitat and systematically sampling at regular intervals along this line. This approach helps researchers collect data on various ecological parameters, such as plant density or species diversity, while minimizing bias and ensuring that the sampling represents the overall environment. It's particularly useful in studying gradients or changes in ecosystems, such as those influenced by environmental factors.
Accidental sampling is a type of nonprobability sampling which involves the sample being drawn from that part of the population which is close to hand. That is, a sample population selected because it is readily available and convenient. The researcher using such a sample cannot scientifically make generalizations about the total population from this sample because it would not be representative enough. For example, if the interviewer was to conduct such a survey at a shopping center early in the morning on a given day, the people that he/she could interview would be limited to those given there at that given time, which would not represent the views of other members of society in such an area, if the survey was to be conducted at different times of day and several times per week. This type of sampling is most useful for pilot testing.
The Mugenda and Mugenda sampling formula is used to determine the appropriate sample size for a study based on a specific population size and the desired margin of error. The formula accounts for the confidence level, population size, and the variability of the responses. It is particularly useful in social sciences for research involving large populations, ensuring that the sample accurately represents the larger group. The formula helps researchers make informed decisions about how many participants to include in their studies.

Random Sampling
Monetary factors are the aspects of an issue that have to do with money. E.g. "While it might prove useful to purchase a helicopter, the monetary factors, such as the cost of purchasing, fueling and maintaining it, together for the cost of a heliport, make it impractical."
I person must be able to understand the definition of liquidity in order to learn about monetary policy. true
Snowball sampling allows for the recruitment of hard-to-reach populations, such as marginalized or hidden communities. It is particularly useful for studying groups where there is no defined sampling frame. Additionally, it can help build trust and rapport with participants as referrals come from within the community.

Work sampling involves recording activities and fixed or random intervals, these activities may or may not be rated.Work sampling is good for measuring things occurring over longer periods like the working week (e.g. contingencies like small/infrequent delays). Time study is good for measuring individual operations and operators to establish standard minute values. Work sampling can also do this and is useful for measuring groups of operators / machines at a time.
