We need to fit n model in n-class classification problem. B. We need to fit n-1 models to classify into n classes. C.b. Qualitative analyses involve using words rather than numbers as the basis of analysis. c. Because the methods used for sampling, data gathering, and analysis are more flexible for qualitative research than for quantitative research, qualitative research is considered a less rigorous approach to nursing research. d.Correct answers: 2 question: Which of the following is true regarding data analysis? a. disciplines and professions do not provide guidance on data analysis. b. data analysis methods should usually be specified in advance before a study begins. c. data analysis methods are generally uniform across disciplines. d. data analysis methods can typically be specified at the close of a study after itData analysis is a growing technology field where the opportunities are immense. And Python is one of the best tools to create data analysis aware applications. So it's highly likely that a lot of programmers are moving to learn Python for data analytics.Exploratory Data Analysis (EDA) is used on the one hand to answer questions, test business assumptions, generate hypotheses for further analysis. On the other hand, you can also use it to prepare

b. Data analysis strategies must usually be specified prematurely before a study begins.

Explanation:

Data analysis is the procedure of amassing or collecting, examining and comparing data. The first procedure in data analysis is the assortment of data. Analysis cannot take place if there is no data. Also, data analysis can happen at all stages of a research or learn about - beginning, right through and at the end.

The major goal of data analysis is to get cheap and helpful knowledge and come up with logical industry selections and as such must be most often performed prematurely sooner than a find out about begins.
