What would be the independent and dependent variables for the following PICOT? P = patients are hospitalized in long-term care I = form a multi-disciplinary team to overview pressure ulcer of patients that have been hospitalized. C = Patients in a hospital without a team intervention O = Patient outcome measurement decrease in pressure ulcer experienced when hospitalized T = one-year period. compare to last year’s numbers

You are conducting a study among diabetic patients to see which type of exercise may benefit their blood glucose levels the most. You will split your patients in to 3 groups (cardio, cardio + weights, and control/no exercise) and after the intervention measure their blood glucose levels and compare the average glucose level between the 3 groups. Which statistical analysis is best suited for the scenario? Select one: Independent t-test Paired t-test One sample t-test ANOVA
Q1/ Differentiate between Descriptive and Prescriptive analytics. Q2/ What is Data Mart? Differentiate between dependent data mart and independent data mart.
You are asked to design a study to examine the relationship between physical activities and incidence of obesity among adolescents. 2.1 What is your independent variable? 2.2 What is your dependent variable? 2.3 How will you measure each, and what level of measurement is this?
Provide your own example of cause-effect relationship of any two variables. Also define what the independent (and dependent) variable is in your statement(s). Keep in mind that the independent variable should be the cause and dependent variable must be the effect. Name of an independent variable: ________________________________________ Name of a dependent variable: ____________________________________ Now show the functional representation of your model. (EXAMPLE) C = f(Y): ___Consumption is a function of Income or Consumption = f (Income) Or, Wage is a...
Q1- How many pairwise comparisons are necessary if a researcher wishes to compare a quantitative variable across a factor with 7 levels? What is the probability of making at least one Type I Error when comparing a quantitative variable across a factor with 7 levels if each pairwise comparison is conducted using a 10% significance level? Q2- Provide an example setting where a One-Way Analysis of Variance (ANOVA) would be an appropriate statistical technique for analysis? Include the following: •...

What is the independent and dependent variable in the research: Effect of a skill demonstration video delivered by smartphone on facilitating nursing student’s skill competencies and self-confidence: A randomized controlled trial study
4. Tamoxifen is a drug often used to treat breast cancer patients. One effect of the drug is to change the levels of cortisol-binding globulin (CBG). One study attempted to see if the effect of Tamoxifen is age dependent on the patients age. The response variable Y is the change in CBG and the covariate X is age. The following summary statistics were reported. n-, 26, Σ i-. 161 3, Σ Vi-28 19. Sr,-3756.96, S,-465.34, Sr,--757.64 (a) Find the least...
