İSTATİSTİK I

This is an observational study. Observational research is non-experimental because nothing (variables, participants etc.) is manipulated or controlled, and as such we cannot arrive at causal conclusions using this approach. the goal is to obtain a snapshot of specific characteristics of an individual, group, or setting.

The pie graph shows a nominal variable.A nominal scale describes a variable with categories that do not have a natural order or ranking. Here, the frequency of the categories of the nominal variable is shown in percentages. Numbers do not indicate that the variable is a numerical variable, it just refers to the frequency of the categories.

Big data refers to the large, diverse sets of information that grow at ever-increasing rates. It encompasses the volume of information, the velocity or speed at which it is created and collected, and the variety or scope of the data points being covered. Big data often comes from multiple sources and arrives in multiple formats. Other concepts are old terms commonly used in statistics.

Big data can be characterized in terms of lots of diverse data elements coming into the organization at the speed of light. Whereas smaller amounts of more homogeneous data elements, coming at a slower rate, in digestible chunks, is representative of small data.
