case study is used: mostly in clinical research used to describe rare events/conditions. It is also used to get a detailed understanding about a person
Key terms: in depth investigation, personal interviews, psychometric tests, direct observation
Advantages: allows in-detail information, efficient and cost effective for rare diseases,
Disadvantages: can’t generalise the results to wider population, difficult to replicate, time intensive
survey is used: to collect data from a larger sample about a specific topic
Key terms: standardised, can be reliable and valid
Advantages: ease of administration and scoring, wider reach to a larger sample, anonymous that allows people to be honest about their answers, ease of statistical analysis, can be helpful in generalising the data to a wider population
Disadvantages: probability of sampling error, response bias
Naturalistic observation is used: to observe behavior in its natural setting as objectively as possible
Key terms: useful for generating hypothesis, natural environment, study social/cultural setting
Advantages: helps in understanding social phenomena that are otherwise difficult to assess/measure, good way to start/generate hypothesis about a line of research
Disadvantages: cannot be generalised, time consuming, observer bias
Correlational studies: is used to assess the relationship between two or more variables
Key terms: independent variable, dependent variable, positive correlation, negative correlation, strong/weak correlation
Advantages: can be used to collect data in a short span of time, establishes cause and effect relationship between the variables
Disadvantages: does not help in understanding the why’s of relationship between the variables
Experiment is used: when manipulation of IV is possible and can be studied under experimental conditions to study its impact on DV
Key terms: independent variable, dependent variable, controlled condition, lab setting, cause and effect
Advantages: easy to control the environment/variables/setting as per the requirements, easy to replicate
Disadvantages: artificial environment/unrealistic, ethical issues with variable control.
General description of method. When is it used? Define Key terms advantages disadvantages Observation": case study...
The naturalistic observation cannot be used to study all issues or phenomena. But, when is this approach the most useful? and when is this approach less useful? This is a 2-part question, examples could be used to further explain the answer.
. Define the following oxygen delivery methods and identify advantages and disadvantages. Method of delivery Advantages Disadvantages Nasal cannula A nasal cannula is a simple, comfortable device u ed for oxygen delivery (Skill 40-4). The two cannulas, about 1.5 cm (0.5 inch) long, protrude from the center of a disposable tube, and are inserted into the nares. Venturi mask The Venturi mask delivers oxygen concentration of 24% to 60% with oxygen flow rates of 4 to 12 L/min, depending on...

Assign the correct research method to the example: Survey Naturalistic Observation Case Study Correlational Design Experimental Research Design Three individuals who have been diagnosed with a rare disorder are studied in detail, and the researcher makes comparisons between them to better understand the disorder A researcher watches and records the social behavior of individuals during a major holiday sale at the mall A sample of individuals is divided into two groups, one of which receives an antidepressant that is being...
Solve 1.Define reactivity as it relates to a scientific experiment. Provide two specific examples of how reactivity might affect a naturalistic observation experiment. 2.Explain the difference between a non-experimental method and an experimental method. Include a description of how each method is performed and identify which type of validity is more associated with each one. 3.Define both qualitative data and quantitative data. Then, identify the purpose, the group who is studied, and the role of the researcher for each type...
(1) determine the type of research design used (experiment, quasi-experiment, correlation, archival, naturalistic observation, etc) (2) ) identify the independent (or predictor) variable(s) and the dependent (or criterion) variable(s), (if any). A. A human resource manager was interested in determining if there was a relationship between employee satisfaction and absenteeism. The professor had 220 employees complete a test of job satisfaction and then compared the scores on this test with the number of days each employee missed work over the...
Case Study Strategies for Negotiation in Business Negotiation plays a vital role in the creation of domestic and international policy In general terms it is defined as a joint decision-making process in which initialy incompatible parties arrive at an agreement thought the exchange of concessions and problem-solving. It normally includes both dialogue with discussion on merits, and bargaining with the use of competitive tactics such as promises or threats (Lang, 1996). The use of negotiation is part of a trend...
python 2..fundamentals of python 1.Package Newton’s method for approximating square roots (Case Study 3.6) in a function named newton. This function expects the input number as an argument and returns the estimate of its square root. The script should also include a main function that allows the user to compute square roots of inputs until she presses the enter/return key. 2.Convert Newton’s method for approximating square roots in Project 1 to a recursive function named newton. (Hint: The estimate of...
