Ted: Ted Ed: What's the Difference Between Accuracy and Precision?
When we measure things, most people are only worried about how accurate, or how close to the actual value, they are. Looking at the process of measurement more carefully, you will see that there is another important consideration:...

Mesc: Samoa School Net: Limits of Accuracy
This module looks at the history of measurement, beginning with non-standard units, the advent of standard units (in this case metric), and when approximation or precision would be needed.
Illustrative Mathematics
Illustrative Mathematics: N q.a.1 and N q.a.3: Felicia's Drive
This task requires students to make some sensible approximations of the amount of gas needed for a drive. They must choose a level of accuracy appropriate to limitations on measurement when reporting quantities. Aligns with N-Q.A.1 and...

Illustrative Mathematics: N q.a: Traffic Jam
This task, codes to all three standards in this cluster, and also offers students an opportunity to practice modeling (MP4). Students must attempt to make reasonable assumptions about the average length of vehicles in the traffic jam and...
Illustrative Mathematics
Illustrative Mathematics: N q.a.3, N q.a.1, N q.a.2: Weed Killer
The principal purpose of the task is to explore a real-world application problem with algebra, working with units and maintaining reasonable levels of accuracy throughout. Aligns with N-Q.A.3, N-Q.A.1, and N-Q.A.2.
Illustrative Mathematics
Illustrative Mathematics: N q.a.3 and S id.a: Accuracy of Carbon 14 Dating I
This task examines, from a mathematical and statistical point of view, how scientists measure the age of organic materials by measuring the ratio of Carbon 14 to Carbon 12. The focus here is on the statistical nature of such dating....
Illustrative Mathematics
Illustrative Mathematics: N q.a.1: Runners' World
This task provides students with an opportunity to engage in Standard for Mathematical Practice 6, attending to precision. It intentionally omits some relevant information. Aligns with N-Q.A.1.
Illustrative Mathematics
Illustrative Mathematics: N q.a.3: Dinosaur Bones
The purpose of this task is to illustrate through an absurd example the fact that in real life quantities are reported to a certain level of accuracy, and it does not make sense to treat them as having greater accuracy. Aligns with N-Q.A.3.
Illustrative Mathematics
Illustrative Mathematics: N q.a.3: Calories in a Sports Drink
The goal of the task is to stimulate a conversation about rounding and about how to record numbers with an appropriate level of accuracy, tying in directly to the standard N-Q.3. Aligns with N-Q.A.3.
