# Data collection and statistics using Python and R

[![Project Status: Concept – Minimal or no implementation has been done yet, or the repository is only intended to be a limited example, demo, or proof-of-concept.](https://www.repostatus.org/badges/latest/concept.svg)](https://www.repostatus.org/#concept)

## Scripting in Python and R
The following gist offers a focus on <b>Data Collection</b>, one of the stages* of the Data Science methodology. We will also perform basic math operations on a single dataframe to see how they render using Python or R.

# Versioning

I used no versioning system for this gist. My repository's status is flagged as <b>active</b> because it has reached a stable, usable state. Original [gist](https://gist.github.com/aiPhD/15873ff613af833f9693e1a595bdfcc6) related to this repository is pending as <b>concept</b>.

* Dataframe used as sample coming from [Spatialkey.com](https://support.spatialkey.com/spatialkey-sample-csv-data/).

## Exercise
* Perform a data collection in `Python` and `R` using `Jupyter`.<br>
⇢ Use the following dataframe from [Spatialkey.com](http://samplecsvs.s3.amazonaws.com/TechCrunchcontinentalUSA.csv).
* How many observations and variables does the dataframe contain? Base your assessment on your scripting outputs.
* Calculate Sum, Min, Max and Mean of variable "raisedAmt" using Python (and Pandas) and using R.<br>
