- Can you please help clarify in layman terms the steps to quantitative and qualiative research methods? Also, could you note the differences. Thank you.The null hypothesis is: That the measured value is zero That the proposed model is not correct and the measured factors have no effect on the pattern That the proposed model is correct and perfectly explains the pattern That the experiment is null and voidAmong patients with schizophrenia (P), does social skills training (I) improve communication skills (O) more than with pharmacological treatment (C) ? What type of quantitative research design would be best for the above PICO question? Descriptive, correlational, independet and dependent variables, quasi-experimental or experiemental? Please provide answer and why? Thanks
- Can I please get help on the last bullet point for the first question: "Do concussions cause memory loss?" And the first 2 bullet points of the second question starting with: "Researchers are studying..." and ending with "A study tracks the long-term..."How do Quasi-experiments differ from other types of studies?An independent variable is… Select one: typically not included in controlled experiments Factor being manipulated factor showing response variable held constant during an experiment
- what is the Expectation and outcome of results, Logical interpretation of the dataand any errors?The following are reasons why randomized control trials (RCTs) are not used to investigate all research questions, except: a. RCTs can be expensive, which can make it difficult if funding is limited b. RCTs can be time-consuming, and it may take months and sometimes years to obtain final results c. For certain research questions and/or certain types of exposure variables, it may not be ethical to conduct an RCT d. RCTs are less valid than observational analytical study designsWhat is control group? Explain the purpose of a control in an experiment.
- what is a controlled experiment?Match the outcomes to whether they are obtained from manipulative experiments or observational studies: 1 2 2 Inference of causality Tests for patterns and possible processes under natural conditions Tests of causes that are difficult to control 1. Manipulative experiments 2. Observational studiesPhysicians practice in a data-intense environment, which provides specific feedback regarding the correctness of their practice. True or false?
