As the Native Americans were worked to death and died of disease, it was mostly "Africans" who were brought in to replace them as laborers, since this is what led to a rapid rise in the Atlantic slave trade.
Answer:
qualitative research
Explanation:
Richard, a research scholar, wanted to do a research study in a subject which does not have a lot of preexisting knowledge. SO he will have to ask basic question to his research subjects in order to get an overall idea about the topic. By doing such he will be able to gain a basic knowledge about the subject he had chosen.
Qualitative research is done to obtain or which aims at expanding and gaining knowledge by asking basic question research participants related to the subjects.
Thus the answer is qualitative research.
Answer: The various types of research designs include surveys, ethnography, experiments, and existing sources.
Surveys provides sociologists with information about how people act or think but can limit sociologists to a particular type of research.
Ethnography collects information through participation or watching a group, however is considered an informal method. Experiments is an artificially created situation that allows a researcher to manipulate variables, but wouldn't be used if researching an entirely new concept. Existing sources (secondary analysis) focuses on using data in ways that weren't initially intended. However if the researcher relies on data collected by someone else they might not find what is needed.
In contrast, expert testimony is admissible only if the witness "qualifies as an expert by virtue of knowledge, skill, experience, education or training" and the testimony provided meets four requirements: increase. Knowledge helps those who know the facts to understand them.
The subject matter of the testimony must be related to the issue at issue. - The usefulness of the testimony outweighs the ill effects it can have.
In the common law system, an expert opinion is usually provided by one of the parties. Evidence must be credible, relevant to the case, conclusive rather than conclusive, and permissible for fact-checking. A fact-finder determines how much weight is given to testimony.
