By using stratified sampling, instead of cluster sampling, Susan is only using a few students from each grade group and not the entire group of1,000students. This allows her to get a representation of the group without having to go to ever...
we use bootstrap techniques to assess our time-series and cross-sectional regression models by testing, in first place, the hypothesis that the independent terms of the time-series models that explain each of the portfolios returns are jointly zero; thus, the models are able to explain the exc...
Other publications have shown that the deep-approach to learning correlates with IM [26], which might explain why more of the invited students from the deep-approach learning type agreed to participate in interviews. The sampling strategy chosen nevertheless attempted to provide a balanced ...
Interpreting model results.The notion that ML is a "black box" is simply false. Yes, not all results are directly interpretable, but you need to be able to diagnose your models to improve them.How can I tell if my model is overfit or underfit? How do I explain these results to busine...
Can someone explain just exactly why xp_cmdshell is such a massive risk?! Can SQL Profiler give you the Missing Index information? Can Symmetric keys be used in a view? Can table-valued parameter be null? Can the "print" command be told not to send a "newline"? Can we alias na...
Explain your agreement or disagreement in detail; (b) Do you think the OFD platforms have been able to implement preventive and proactive measures to protect against the spread of COVID-19?; (c) What are your different grievances, fears, and worries related to using the OFD platforms during...
Did you know that sensibly partitioning your hard drive or, if it's already partitioned, simply swapping the positions of your audio and sample partitions could result in a significant improvement in PC audio performance? We explain the whys and wherefor
Explain how to find mean and standard deviation from percentiles. Explain how two samples can have the same mean but different standard deviation. How do Normal Distributions compare with Sampling Distributions? Could the median ever be greater than the first quartile in a data set consi...
Interactive computer simulations are commonly used as pedagogical tools to support students’ statistical reasoning. This paper examines whether and how these simulations enable their intended effects. We begin by contrasting two theoretical frameworks—
These are biologically important questions because the answer to the first two questions could impact our understanding of how protein homeostasis is maintained in cells. The answer to the final question would help to explain how synonymous mutations can have long term impacts on protein structure and...
