What do comparative and descriptive investigations have in common?

What do comparative and descriptive investigations have in common?

Descriptive Investigation: Involve describing and/or quantifying parts of a natural system. Example – observing cells under a microscope and diagramming what is seen. Comparative Investigation: Involve collecting data on collecting data on different populations/organisms, under different conditions (ex.

What are all the steps of a descriptive investigation?

Be sure to have:

  • Make an observation about a phenomenon (qualitative and/or quantitative)
  • Ask a research question.
  • Hypothesize a possible answer for your question.
  • Create a procedure to test your hypothesis.
  • Identify what you are testing.
  • Identify your control group/experimental group.

Which of the following is the best example of a comparative investigation?

Identifying the boiling points of three different liquids, and using a hand lens to observe the external anatomy of 2 different insects are examples of comparative investigations.

What are the benefits of comparative investigation?

Benefit of comparative investigation is that we can get descrete information about specific breed or species. It is important for the study of behaviour of many organisms. The working and behaviour of various natural aspects can be found. Many natural phenomenon has been found by this method.

Is a comparative study qualitative or quantitative?

Quantitative analysis is much more frequently pursued than qualitative, and this is seen by the majority of comparative studies which use quantitative data. The general method of comparing things is the same for comparative research as it is in our everyday practice of comparison.

What is the limitation of comparative investigations?

Answer: Limitation of comparative investigation is that when it is done on a huge population, huge amount cost is required. Explanation: Benefit of comparative investigation is that we can get descrete information about specific breed or species. It is important for the study of behaviour of many organism.

Are comparative investigations repeatable?

Which is a limitation of comparative investigations? – They give results that are usually not repeatable by other scientists. -They might show variable relationships that are not actually cause and effect. -They can usually only be conducted in labs instead of in natural environments.

Which kind of investigations are meant to provide large amounts of information?

Quantitative, as opposed to qualitative investigations provide large amounts of information about a wide range of variables. Quantitative investigations yield numerous results – they are all about the quantity, or large number of results, whereas qualitative are more about the quality.

What are the different methods of primary data collection?

5 Traditional Methods of Primary Data Collection

  • Direct Personal Interviews. The investigator personally meets concerned individuals and collects the required information from them.
  • Indirect Personal Interviews.
  • Collection through Questionnaires.
  • Collection through Enumerators.
  • Collection through Local Sources.

What are primary and secondary data collection methods?

Primary data sources include; Surveys, observations, experiments, questionnaires, focus groups, interviews, etc., while secondary data sources include; books, journals, articles, web pages, blogs, etc. These sources vary explicitly and there is no intersection between the primary and secondary data sources.

What is primary data in research methods?

Primary data is a type of data that is collected by researchers directly from main sources through interviews, surveys, experiments, etc. Primary data are usually collected from the source—where the data originally originates from and are regarded as the best kind of data in research.

What is a secondary research method?

Secondary research or desk research is a research method that involves using already existing data. Existing data is summarized and collated to increase the overall effectiveness of research. Secondary research includes research material published in research reports and similar documents.

What are some examples of primary research?

Examples of primary research are:

  • Interviews (telephone or face-to-face)
  • Surveys (online or mail)
  • Questionnaires (online or mail)
  • Focus groups.
  • Visits to competitors’ locations.

What is difference between primary and secondary research?

Primary research is one that involves the gathering of fresh data. On the contrary, Secondary research is a research method which involves the use of data, already collected through primary research.

Is primary research qualitative or quantitative?

Primary data and secondary data can be either quantitative. (numerical) or qualitative. (verbal). Quantitative research is usually based on a large-scale sample of respondents and is typically expressed in numeric terms such as averages, percentages, or statistics.

What do comparative and descriptive investigations have in common?

Descriptive Investigation: Involve describing and/or quantifying parts of a natural system. Example – observing cells under a microscope and diagramming what is seen. Comparative Investigation: Involve collecting data on collecting data on different populations/organisms, under different conditions (ex.

Do comparative investigations require a hypothesis?

In both comparative and experimental investigations, a hypothesis should be established.

What steps are included in a descriptive investigation?

Be sure to have:

  • Make an observation about a phenomenon (qualitative and/or quantitative)
  • Ask a research question.
  • Hypothesize a possible answer for your question.
  • Create a procedure to test your hypothesis.
  • Identify what you are testing.
  • Identify your control group/experimental group.

What does a control group show in a experimental investigation?

A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable’s effects on the experiment and can help rule out alternative explanations of the experimental results.

What does a control group show in an experimental investigation quizlet?

A control group is a group separated from the rest of the experiment where the independent variable being tested is not exposed. You just studied 4 terms!

What was the primary difference between the control and experimental groups in this experiment?

The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is “controlled” or held constant in the control group.

Which kind of investigations allow for control of variables?

Experimental investigations include a method in which a “fair test” is created and variables are actively planned, managed, and measured in an attempt to gather testimony to confirm or negate a causal relationship.

What is limitation of descriptive investigation?

A descriptive study is limited to a description of the occurrence of a disease in a population. It is unable to test hypotheses.

What is a benefit of conducting a comparative investigation rather than a descriptive investigation?

What is a benefit of conducting a comparative investigation rather than a descriptive investigation? It will be less time-consuming to collect data about elements. It will show a cause-and-effect relationship between two properties of elements.

What types of questions can most likely be answered through scientific investigation?

Explanation: Testable questions ask about objects, organisms, and events in the natural world. Testable questions can be answered through investigations that involve experiments, observations, or surveys. Testable questions are answered by collecting and analyzing evidence that is measurable.
