Data aggregation

The process of gathering data from multiple sources in order to combine it into a single summarized collection

Puzzle pieces = data
Organization = aggregation
Pile of pieces = summary
Putting the pieces together = gaining insights

The aggregation process helps to identify trends, make comparisons, and gain insights that wouldn't be possible if each of the data elements were analyzed individually.

Data can also be aggregated over a given time period to provide statistics such as:

Averages
Minimums
Maximums
Sums

Functions play a significant role make data aggregation possible.

Subquery or nested query is a query within another query, which is often used in data aggregation.

Storytelling with Data

* Stories are powerful tools for teaching and sharing knowledge, not just entertainment. * Data analysts are storytellers who use data, visuals, and narratives to inform and persuade. * A data narrative explains the origin and purpose of data, providing context to findings. * Visuals aid in bringing data insights to life and making

Interpreting Data

* The final step in the OSEMN Framework is interpreting data analysis results. * Interpretation involves generating insights and telling a story with the data. * This week focuses on how to draw conclusions from analysis and create compelling data stories. * The course will cover approaches to data interpretation and storytelling techniques. * A

Modeling Data

* Modeling is the fourth stage of the OSEMN (Obtain, Scrub, Explore, Model, iNterpret) data analysis cycle. * This phase involves using data to make predictions through mathematical models. * Models can range from simple linear regressions to complex machine learning algorithms. * The primary function of models is to discover hidden patterns in

Scrubbing Data

* Scrubbing data is the second phase of the OSEMN framework, focusing on cleaning and preparing data for analysis. * The scrubbing process transforms raw, dirty data into clean, usable data. * Four main tasks in data scrubbing: * Removing duplicates * Formatting records * Solving for missing values * Checking records for mistakes or wrong values
