COMPLETE SOLUTIONS GRADED A++ LATEST UPDATE
What is the system of measurement used in the US?
The English/Imperial system. (Inches, feet, gallons)
What is the system of measurement used for most countries?
The Metric system. (meters, grams, liters)
What data use descriptive words and names?
Qualitative Data. (Names, colors, smells)
What data uses numerical values?
Quantitative Data. (Test scores, weight, shoe size)
How to calculate average/mean?
Average Formula:
Sum of all numbers/ the amount of numbers.
(5+5+5+5/4: average=5)
How to calculate range?
The greatest number value- the smallest number value.
(150-50: range= 100)
How to transform Celsius to Fahrenheit?
C to F formula:
F= 1.8C + 32
, 1.8 x (100) + 32
= 212 Fahrenheit
How to transform Fahrenheit to Celsius?
F to C Formula:
C= F - 32/1.8
98- 32/1.8
=36.7 Celsius
Difference between random and systematic error.
Random error: due to changes in variation (blood pressure)
Systematic error: experimental deficiencies (errors in temperature due to the room
thermometer)
What is the precision of lab materials?
Precision: the smallest unit of subdivision
(a ruler's smallest unit is 1mm, then p=1mm)
What are the significant digit rules?
1. All non-zeros and any zeros contained between non-zeros.( 34567= 5sf)
2. No leading zeros.( 0.00034= 2sf)
3. trailing zeros count only with decimal point. (0.00052600= 5sf)
4. Trailing zeros may count if there is no decimal.( 190000= 2sf)
What are the two categories of Quantitive data? What is the difference?
Discrete and Continuous Data:
