What is the difference between qualtatative and qauntative?
Some methods provide data which are quantitative and some methods data which are qualitative. Quantitative methods are those which focus on numbers and frequencies rather than on meaning and experience. Quantitative methods (e.g. experiments, questionnaires and psychometric tests) provide information which is easy to analyse statistically and fairly reliable. Quantitative methods are associated with the scientific and experimental approach and are criticised for not providing an in depth description. Qualitative methods are ways of collecting data which are concerned with describing meaning, rather than with drawing statistical inferences. What qualitative methods (e.g. case studies and interviews) lose on reliability they gain in terms of validity. They provide a more in depth and rich description.
What is statistical data and statistical methods?
Statistical Data: Statistical data science involves the collection, interpretation, and validation of data. It involves a variety of statistical operations performed with some statistical tools without having prior statistical knowledge. There are several software packages for performing statistical data analysis, including SAS (Statistical Analysis System), SPSS (Statistical Package for Social Sciences), etc. There are Different Types of Statistical data : Numerical Data: The data can serve as a measure, such as a person's height, weight, IQ, or blood pressure, or they can serve as a count, such as the number of shares a person owns, a dog's number of teeth, or the number of pages in a book you finish before falling asleep. 2.Categorical data : Categorical data are attributes that can take on numerical values (such as the numbers "1" and "2" indicating male and female, respectively). Ordinary Data : In ordinal data, categorical data are mixed with numerical data. The data fall into categories, but the numbers placed on the categories have meaning. For example, rating a restaurant on a scale from 0 (lowest) to 4 (highest) stars provides ordinal data. Statistical Methods: It is a statistical method that extracts information from research data and provides ways to assess the robustness of research outputs with mathematical formulas, models, and techniques. There are different types of Statistical Methods: Descriptive Methods : A descriptive method involves every step in the analysis and interpretation process, such as the collection of data, the tabulation of data, the measurement of central tendency, the measurement of dispersion, as well as the analysis of time series. This method is also otherwise called descriptive statistics . 2 Analytical methods : This method comprises all those methods which help analyze and compare any two or more variables. These include correlation analysis, regression analysis, attribute association analysis, and the like. This method is also referred to as analytic analysis. Inductive Methods :A generalization procedure consists of all procedures that lead to an estimation of a phenomenon using random observations or partial data, such as interpolation and extrapolation. This methods is also otherwise called inductive statistics. Inferential Methods :In other words, it is a method of drawing conclusions about the characteristics of a population based on samples of data. This method includes theories such as sampling theory, different tests of significance, statistical control, etc. This method is also otherwise called inferential statistics. Applied Methods :These methods are used to solve real-life problems, such as statistical quality control, sampling surveys, linear programming, inventory control, and other procedures.

What is the difference between Supervised and unsupervised methods in data mining?
Unsupervised Learning• The model is not provided with the correct resultsduring the training.• Can be used to cluster the input data in classes onthe basis of their statistical properties only.• Cluster significance and labeling.• The labeling can be carried out even if the labels areonly available for a small number of objectsrepresentative of the desired classes.Supervised Learning• Training data includes both the input and thedesired results.• For some examples the correct results (targets) areknown and are given in input to the model duringthe learning process.• The construction of a proper training, validation andtest set (Bok) is crucial.• These methods are usually fast and accurate.• Have to be able to generalize: give the correctresults when new data are given in input withoutknowing a priori the target.
