How do you find data sets for data analysis?
A sample data set contains a part, or a subset, of a population.
The size of a sample is always less than the size of the population from which it is taken. [Utilizes the count n - 1 in formulas.] Example: The sample may be "SOME people living in the US.".
How do you perform data analysis on a data set?
A simple example of data analysis can be seen whenever we make a decision in our daily lives by evaluating what has happened in the past or what will happen if we make that decision.
Basically, this is the process of analyzing the past or future and making a decision based on that analysis..

What is a dataset in data analysis?
A Data Set is a container that holds the data you upload to Analytics.
Data Sets control how uploaded data gets joined with existing data.
You configure Data Sets at the Property level.
Data Sets must be associated with at least one View, and can be associated with multiple Views..

What is an example of a good dataset?
A data set is a collection of numbers or values that relate to a particular subject.
For example, the test scores of each student in a particular class is a data set.
The number of fish eaten by each dolphin at an aquarium is a data set..
Where to get data for data science projects
The dataset should be rich enough to let you play with it, and see some common phenomena.
In other words, it must have at least a few thousand rows (\x26gt; 3.5 − .
- K), and at least 20 − 25 columns.
Of course, larger is welcome.
The dataset should have a reasonable mix of both continuous and categorical variables.
