Research Methods #2

QuestionAnswer
What is research proposal the broader plan & justification of the entire research project
What is research design how will the study be carried out
What are 3 Research purposes 1, Descriptive = Describe 2, Exloratory = Discover 3,Causal = Explain cause-effect
What are 2 Data Supply 1, Internal / In-house Research = researching for yourself 2,External = getting outside organization to conduct research
What are 3 Research Setting 1, Field Research= Real-world setting 2,Desk Research = collecting already existing data 3,Laboratory research = Controlled environment
What is in sample 1, element 2,subject 3,sampling unit 1, element = single member of population 2,subject = single member of the sample 3,sampling unit = "who" or "what" is available for selection during sampling
What are 4 types of probability sampling 1, Simple random sampling 2, Systematic random sampling 3, Stratified sampling 4,Cluster sampling
What are 4 types of non-probability sampling 1, Convenience sampling 2,Purposive sampling 3, Quota sampling 4,Snowball sampling
What are 3 main differences between probability & non-probability sampling 1, probability sampling have known change of selection 2, non-probability is based partly on judgment/accessibility 3, probability have stronger basic for generalization
What is advantage and disadvantage of Purposive Sampling Advantage = if research is right he may reach particulatly informative cases Disadvantage = selection of respondent may be biased
What is difference between simple random sampling and systematic random sampling Simple random sampling = "purest" form of probability sampling Systematic random sampling = selecting elements at regular intervals
What is difference between Stratified & Cluster Sampling Stratified sampling = divide into groups >> sample from every group Cluster sampling = divide into groups >> randomly select some groups
How large should be a qualitative sample until we reach data saturation
What are 4 rules of thumb for sample size General 30<n<500 30 x Nr. of subcategories 10 x Nr. of Variables 20x Conditions of Experiments
What is Non-coverage Error if we fail to include part of the target population
What is Non-Response Error the people selected for the sample fail to respond & potentially creating bias
What is measurement represent a phenomenon systematically with number or other symbols
What are two types of measurements 1, direct observable = we count them directly 2,Indirect observable = you obtain a report or representation of it
What is conceptual and operational definition of a construct Conceptual = What does this construct mean? Operational = How exactly will I measure it?
What is Operationalization process of converting an abstract construct into measurable indicators

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
