Data is the foundation of data science. Data is the systematic record of a specified characters, quantity or symbols on which operations are performed by a computer, which may be stored and transmitted. It is a compilation of data to be utilised for a certain purpose, such as a survey or...
What is the appropriate measure of central tendency for a variable measured on a categorical scale? a) mean. b) median. c) mode. d) the mean or the mode. e) all of the above would be appropriate. What type of correlation is the example below? Researchers have ...
The better the score for the metric you want to optimize for, the better the model is considered to "fit" your data. It stops once it hits the exit criteria defined in the experiment. Using Azure Machine Learning, you can design and run your automated ML training experiments with these ...
Quantitative (Numerical) vs Qualitative (Categorical) There are other ways of classifying variables that are common in statistics. One is qualitative vs. quantitative. Qualitative variables are descriptive/categorical. Many statistics, such as mean and standard deviation, do not make sense to compute ...
Learn how to perform a Chi-Square Test easily with this step-by-step guide. Perfect for beginners looking to grasp the basics of statistical analysis.
When we have to predict the value of a categorical (or discrete) outcome we use logistic regression. I believe we use linear regression to also predict the value of an outcome given the input values. Then, what is the difference between the two methodologies? machine-learning data-...
For example, while categorical data, a type of thematic analysis, can be measured and counted, the data is still considered qualitative because the groups are measured by their open-ended responses, or words, rather than numbers. Phone numbers are also an example of numerical data that wouldn’...
