Selecting the right data
Following are some data-collection considerations to keep in mind for
your analysis:
How the data will be collected
Decide if you will collect the data using your own resources or receive
(and possibly purchase it) from another party. Data that you collect
yourself is called first-party data.
Data sources
If you don’t collect the data using your own resources, you might get
data from second-party or third-party data providers. Second-party data
is collected directly by another group and then sold. Third-party data is
sold by a provider that didn’t collect the data themselves. Third-party
data might come from a number of different sources.
Datasets can show a lot of interesting information. But be sure to choose
data that can actually help solve your problem question. For example, if
you are analyzing trends over time, make sure you use time series data
— in other words, data that includes dates.
How much data to collect
If you are collecting your own data, make reasonable decisions about
sample size. A random sample from existing data might be fine for some
projects.
Other projects might need more strategic data collection to focus on
certain criteria. Each project has its own needs.

If you are collecting your own data, decide how long you will need to
collect it, especially if you are tracking trends over a long period of time. If
you need an immediate answer, you might not have time to collect new
data. In this case, you would need to use historical data that already
exists.
Observation is the method of data-collection most often used by scientists.
