There are two types of quantitative data: discrete and continuous. Suppose the standard deviation for the PSAT math score is 1.5 (a) Hom(R2,R8)\operatorname{Hom}\left(\mathbf{R}^2, \mathbf{R}^8\right)Hom(R2,R8), For example, business analysts predict how much revenue will come in for the next quarter based on your current sales data. Measurements like weight, length, height are not classified under discrete data.

The quantitative interview is structured with questions asking participants a standard set of close-ended questions that dont allow for varied responses. PART 2 - PRACTICE PROBLEMS A.) Weight in kilograms is aquantitativevariablebecause it takes on numerical values with meaningful magnitudes and equal intervals. does not have a number. 2. Discrete data. Each data point is on its own (not useful for large groups) and can create doubts of validity in its results. A random variable can be discrete Continuous, when the variable can take on any value .

The COVID-19 pandemic has provided a unique circumstance for the study of resilience, and clergy resilience has garnered increased research attention due to greater recognition that religious/spiritual leaders are at risk for elevated levels of anxiety and burnout.

The numbers used in categorical or qualitative data designate a quality rather than a measurement or quantity. A categorical variable doesnt have numerical or quantitative meaning but simply describes a quality or characteristic of something. a capital letter, The probability distribution of a Qualitative data is descriptive data that is not expressed numerically.
