How do scientists gather and analyze data?
Gather Data
Scientists can gather their data by
observing the natural world, performing an experiment in a laboratory
, or by running a model. Scientists decide what strategy to use, often combining strategies. Then they plan a procedure and gather their data.
What do scientists do to analyze data?
Scientists perform
experiments
in order to verify whether their explanations of natural phenomena are correct. The results from such experimental investigations are called experimental data and the decision of whether or not a hypothesis is to be rejected is made after a careful analysis of the experimental data.
Do data scientists code?
In a word,
yes
. Data Scientists code. That is, most Data Scientists have to know how to code, even if it’s not a daily task. As the oft-repeated saying goes, “A Data Scientist is someone who’s better at statistics than any Software Engineer, and better at software engineering than any Statistician.”
