Which basic component of a research project answers the question: what is being studied?

  1. A.Subject matter
  2. B.Methodology
  3. C.Philosophical bases
  4. D.Research design
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ A Subject matter

ምክንያቱ

According to the textbook, any research project has three main components: the subject matter (what is being studied), the methodology or approach (how it is being studied), and the philosophical bases.

ጥያቄ 2

Which of the following is categorized as a primary data source in geographical research?

  1. A.A statistical report published by a government ministry
  2. B.Focus group discussions conducted directly by the researcher
  3. C.An article published in an international geography journal
  4. D.A historical diary stored in a public library
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ B Focus group discussions conducted directly by the researcher

ምክንያቱ

Primary data is firsthand, original data collected by the researcher for a specific project. Examples include surveys, interviews, field observations, and focus group discussions.

In which level of measurement is there always a meaningful absolute zero?

  1. A.Nominal
  2. B.Ordinal
  3. C.Interval
  4. D.Ratio
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ D Ratio

ምክንያቱ

In ratio measurement, an absolute zero exists, which allows researchers to construct meaningful fractions, ratios, and counts.

ጥያቄ 4

Which motivation for conducting geographic research specifically aims at forecasting future events and behaviors resulting from a phenomenon?

  1. A.Exploration
  2. B.Explanation
  3. C.Description
  4. D.Prediction
መልሱንና ምክንያቱን ያሳዩ

Which group of maps is identified in the textbook as the main examples for portraying feature attribute values as a volume (statistical surface)?

  1. A.Dot maps, Choropleth maps, and Isarithm maps
  2. B.Topographic maps, Cadastral maps, and Sketch maps
  3. C.Flow maps, Network maps, and Mental maps
