What are the types of errors in data collection?
Two major types of error can arise when a sample of observations is taken from a population: sampling error and non-sampling error. Non-sampling errors are more serious and are due to mistakes made in the acquisition of data or due to the sample observations being selected improperly.
What are the errors in data collection?
The total error of the survey estimate results from the two types of error: sampling error, which arises when only a part of the population is used to represent the whole population; and. non-sampling error which can occur at any stage of a sample survey and can also occur with censuses.
Is big data good or bad for us?
Although it has amazing potential to improve our world, it can easily be abused for the sole purpose of tracking behavior to make money or, even more evil, tracking dissidents to eliminate them. Although many are unhappy about it, the way our government (and megacorps) currently use big data is tolerable.
What are the most common pitfalls in big data?

What are the most cost-effective ways to implement a data platform?
Missing/sparse data, null values, and human errors, must all be cleansed. Avoid relying on un-proven assumptions or weak co-relations. Instead, collect as much data as possible and let the data speak for itself. This is very cost effective with the implementation of a data platform.
