Motivation can be extrinsic, i.e., driven by external rewards, or intrinsic, i.e., driven by internal factors. Intrinsic motivation is the most effective and must ...
UCI Machine Learning Repository, or government open data portals. These platforms provide datasets for various fields, including finance, healthcare, and more. If you’re working in Excel, you can also use add-ins like Power Query to import large datasets directly from online sources. ...
In the Wrapper sample application, when a student registers for classes, the student's account is charged for the classes and the balance of the student's account is updated. In addition, students can get information about their account balances. The Wrapper sample application incorporates an ...
Creating Excel sample data consumes hours upon hours of my time. This time consuming task of course plagues many Excel trainers, teachers, bloggers and even Excel students and learners. Here are a few good reasons why investing in Excel sample data sets might be for you: ...
The degrees of freedom number expresses the fact that you are measuring the variability of all n data values about their sample averages but have lost k degrees of freedom because k different sample averages were estimated. For the supplier quality example, the within-sample variability (with n...
While calculating statistics for an entire population would typically be ideal, this may not always be possible due to time and/or money constraints. To remedy this, sample statistics can be calculated to represent the whole population. Sample statistics are any number computed from data that repre...
students who respond to a flyer posted on a bulletin board on a university campus that seeks participants in a survey. A quota sample sets quotas, using convenience sampling, to obtain the samples. For instance, a quota sample might be filled by some number of customers at shopping malls in...

What is numerical data in statistics? What relationship do sample size and width of confidence intervals have? Suppose you wanted to know the proportion of students who wear glasses on campus and you went ahead and survey only the students in your class. What sampling technique were you using?
We study generalization of intervention effects across several simulated and real-world samples. We start by formulating the concept of the ‘background’ of a sample effect observation. We then formulate conditions for effect generalization based on a s
