Question
Your study wishes to determine if the consumption of food can lead to obesity. Food consumption is: Select one: Nominal level Ratio level the independent variable The dependent variable You are working with older adults in a geriatric care unit. Your nurse manager asks you to measure the intake of desserts in the dining half. You consumed 0 desserts, 27 adults consumed t dessert, and 33 adults consumed 2 or more desserts. What level of measurement is dessert consume Select one: interval Ratio Critical NormalExplanation / Answer
The variable(s) we measure as the outcome of interest is the dependent variable, or response. The variable that determines the population a measurement arises from is the independent variable (or predictor). For instance, if we wish to compare bio availabilities of various dosage forms, the dependent variable would be AUC (area under the concentration–time curve), and the independent variable would be dosage form. The labels dependent and independent variables have the property that they imply the relationship that the independent variable “leads to” the dependent variable’s level.
So the food consumption is the independent variable.
The level of measurement is dessert consumption is ordinal.
Because in quantitative data at the ordinal level of measurement can be ordered, however differences between values are meaningless. An example of data at this level of measurement is any form of ranking.
Ordinal variables have levels that do follow a distinct ordering.
Examples in the medical field typically such as: vast improvement, moderate improvement, no change, moderate degradation, vast degradation/death.
A study of random sample of college students finds that the true average college students receive a mean of 5 hours of sleep per night. The mean is parameter.
Parameters are numerical descriptive measures corresponding to populations. Since the population is not actually observed, the parameters are considered unknown constants.
