Data/ Measurement

Metric- 

·     Volume (ml) 
·     Distance (m) 
·     Temperature (c) 
·     weight (grams) 

Types of Data- 

·     Ratio: True zero (weight, volume, length) 
·     Interval: arbitrary zero (temp, time of day, date) 
·     Ordinal: no number value (dark vs. light) 
·     Nominal: non- numeric (colors) 

Continuous- infinite number of values between two individuals (ex: 2.7, 7.701, 2.702) 

Discrete- integers (ex: 35 seals, 22 cells) 

Accuracy- measuring device (ex: nearest .1 g) 

Precision- researcher (how close they are to repeated measurement) 

Implied Range: value between data 

Rounding rules: If x> 5, then round
