Your stated uncertainty should have only one significant figure if possible.
A bar of gold is measured with the ruler shown the length of the bar should be reported as.
Stem and leaf plot.
Thus a ruler a can give the measurements 2 0 cm and 2 5 cm.
Shown using the equation triangle to the right which offers a quick way of rearranging the values in order to derive related formulas.
2 4 cm o a 3 cm b 3 0 cm c 2 7 cm d 2 cm.
Five students measured the same line with the ruler shown below.
A stem typically for the highest place value and a leaf for the other place values.
A bar of gold is measured with the ruler shown below.
Magnification size and scale bars cells are extremely small but knowing the sizes of objects viewed under the microscope can be really useful.
This enters the scale into the lower measure at scale dialog.
For example the person measuring the length of a stick with a ruler notices that the stick length seems to be somewhere in between 36 6 cm and 36 7 cm and he or she must estimate the value of the last digit.
Five is always best if you can manage it.
A bar of gold is measured with the ruler shown.
You would expect him to be taller than 1 ruler but not as tall as 3 rulers.
Measured length measure at scale from any on screen image use a full scale ruler to measure a known measurement from an image on screen.
The results reported by the students were as follows.
In the ib physics laboratory you should take 3 to 5 measurements of everything.
2 4 cm the uncertainty in the length of the bar should be reported as.
B ruler b can give the measurements 3 35 cm and 3 50 cm.
It should be noted that the last digit in a measured value has been estimated in some way by the person performing the measurement.
The volume of the liquid is.
In the calculate scale dialog enter this measurement into measured length and the actual full scale measurement into full scale length hit calculate scale to calculate the scale.
The length of a rod is measured using part of a metre rule that is graduated in millimetres as shown below.
4 51 cm 4 55 cm 4 53 cm 4 5 cm and 4 6 cm.
A stem and leaf plot breaks each value of a quantitative data set into two pieces.
Imagine the length of the objects you are estimating or imagine measuring them in relation to other objects.
The length of the bar should be reported as.
Ruler a has an uncertainty of 0 1 cm and ruler b has an uncertainty of 0 05 cm.
For example if you are using this graph to review student test scores of 84 65 78 75 89 90 88 83 72 91 and 90 the stems would be 6 7.
Imagine a meter ruler meter stick next to a tall man.
Or should an insect be measured in meters or millimeters yards or inches.
Which measurements are consistent with the metric rulers shown in figure 2 2.
A sample of a liquid with a density of 2 1 g ml has a weight of 4 242 g.
2 cm 2 0 cm 2 05 cm 2 5 cm 2 50 cm.
