Final answer:
Raw data is the actual measurements or observations made, while primary data is firsthand accounts or original sources that provide a firsthand account. Raw data needs to be analyzed and interpreted, while primary data allows researchers to create their own analysis.
Step-by-step explanation:
The difference between raw data and primary data lies in their origin and purpose. Raw data refers to the actual measurements or observations made in an investigation, while primary data refers to firsthand accounts or original sources that provide a firsthand account of an event or period. Raw data generally needs to be analyzed and interpreted, typically using statistics, to determine if it supports a hypothesis. Primary data, on the other hand, allows researchers to create their own analysis based on the original source material.
