first major error is that many graphs do not present data effectively. In order to make an effective graph, you should follow some standard conventions: Use either linear or log scales on both x and y axes. Many students used arbitrary scales or simple labelled their data points on the x and y axes. Standard scales make it easier to interpret a graph. Nonstandard scales percent error when true value is 0 make data hard to decipher. Make your graphs at least 7.5 cm (three inches) tall and 10cm (four inches) wide to ensure clarity. Smaller graphs hide smaller variations in the data; computer-generated graphs are great but not necessary. Label all axes and traces. Also, do not put more than two traces on a graph unless you are trying to show a progression of data. If there are two traces or more on a graph, use different marks for the data points; i.e. x's for trace one, o's for trace two, etc. Use two or more colors for the traces if practical. Tables Another weakness in lab reports is the style of tables used. Use a vertical table (an independent variable column next to the dependent variable columns) whenever you have the numerical data available. Please do not use horizontal tables; they are very hard to read and thus do not present your data effectively. Use your ruler to organize your tables and make them easier to read. Error Analysis Writing: "...the measurements agree pretty well with the expected values..." does not mean a thing. It is important to do good error analysis. Usually, this shou

The formula is given by: The experimental value is your calculated value, and the theoretical value is your known value. A percentage very close to zero means you are very close to your targeted value, which is good. It is always necessary to understand the cause of the error, such as whether it is due to the imprecision of your equipment, your own estimations, or a mistake in your experiment.Example: The 17th century Danish astronomer, Ole Rømer, observed that the periods of the satellites of Jupiter would appear to fluctuate depending on the distance of Jupiter from Earth. The further away Jupiter was, the longer the satellites would take to appear from behind the planet. In 1676, he determined that this phenomenon was du
"sizes" of the things being compared. The comparison is expressed as a ratio and is a unitless number. By multiplying these ratios by 100 they can be expressed as percentages so the terms percentage change, percent(age) difference, or relative percentage difference are also commonly used. The distinction between "change" and "difference" depends on whether or not one of the quantities being compared is considered a standard or reference or starting value. When this occurs, the term relative change (with respect to the reference value) is used and otherwise the term relative difference is preferred. Relative difference is often used as a quantitative indicator of quality assurance and quality control for repeated measurements where the outcomes are expected to be the same. A special case of percent change (relative change expressed as a percentage) called percent error occurs in measuring situations where the reference value is the accepted or actual value (perhaps theoretically determined) and the value being compared to it is experimentally determined (by measurement).

When y is a reference value (a theoretical/actual/correct/accepted/optimal/starting, etc. value; the value that x is being compared to) then Δ is called their actual change. When there is no reference value, the sign of Δ has little meaning in the comparison of the two values since it doesn't matter which of the two values is written first, so one often works with |Δ| = |x - y|, the absolute difference instead of Δ, in these situations. Even when there is a reference value, if it doesn't matter whether the compared value is larger or smaller than the reference value, the absolute difference can be considered in place of the actual change. The absolute difference between two values is not always a good way to compare the numbers. For instance, the absolute difference of 1 between 6 and 5 is more significant than the same absolute difference between 100,000,001 and 100,000,000. We can adjust the com
