Observe is the root word of observation.
The root word "spec" comes from the Latin word "specere," which means "to look" or "to see." This root is commonly used in words related to vision, sight, or observation. For example, words like "spectacle," "spectator," and "inspect" all contain the root word "spec."
The word "quantitative" is from the root word quantity. So, a quantitative observation is one that can be quantified or counted. Any time you count or physically measure something, it is a quantitative observation. Since it is your homework you should come up with your own examples :)
