2
New cards

Kelvin to Celsius

Celsius to Fahrenheit

C=K-273.15

(°C) = ((°F) − 32) × 5/9

3
New cards

mean

arithmetic average of data

add up all values in dataset and divide total by number of values

4
New cards

median

middle value of data set

5
New cards

range

difference between largest and smallest values of data set

6
New cards

standard deviation and variance

measure of how much variation exists in data set

average of squared differences from the mean (sd squared)

<p>measure of how much variation exists in data set</p><p>average of squared differences from the mean (sd squared)</p>
7
New cards

precision and accuracy

how close repeated measurements are to each other

how close the measured values are to the known value

8
New cards

procedure

measurement of length in metric and US units

  • measure height 3 times in both, know conversion

measurement of volume in metric and US units

  • fill beaker 50 mL and check accuracy with graduated cylinder 3 times read meniscus

measurement of mass in metric and US units

  • weigh penny 3 times

measurement of temperature

  • record temperature of ice and hot water

record mean and SD of all trials
