1B-Mathematics, Measurement & Data Manipulation

Question 1

SI Units

Answer 1

measurement in science- Systeme international d’unites that include 7 base units

Question 2

Precision

Answer 2

how close several measured values are to each other, indicator to data scatter

Question 3

Accuracy

Answer 3

how close the measured values are to the true or actual value

Question 4

Significant Figures

Answer 4

critical to accurate measurement, tell readers how well to measure raw data

Question 5

Scientific Notation

Answer 5

is a short way to express large numbers
5.01x10^13 = 50,100,000,000,000.
5.01 = coefficient
10 = base
13 = exponent(+move to rt, -move to left)

Question 6

Line graphs

Answer 6

compare data, shows continuous change, showing effects over time

Question 7

Bar graphs

Answer 7

represent discrete blocks of data that are not continuous, shows rank order of trends

Question 8

Pie graphs

Answer 8

designed to show the component parts of a whole/persentages

Question 9

Extrapolation & Interpolation

Answer 9

estimated values on the graph within or beyond what was collected

Question 10

Percent error formula

Answer 10

(Theoretical value-Experimental value/Theoretical value)x100
