But no matter how hard you try, error in your data is unavoidable. In this lesson, you'll learn about the types of unavoidable experimental error to be on the lookout for and how to reduce their occurrence in your data.

For example, if two different people measure the length of the same rope, they would probably get different results because each person may stretch the rope with a different tension. The best way to minimize definition errors is to carefully consider and specify the conditions that could affect the measurement. Failure to account for a factor (usually systematic) - The most challenging part of designing an experiment is trying to control or account for all possible factors except the one independent variable that is being analyzed. For instance, you may inadvertently ignore air resistance when measuring free-fall acceleration, or you may fail to account for the effect of the Earth's magnetic field when measuring the field of a small magnet. The best way to account for these sources of error is to brainstorm with your peers about all the factors that could possibly affect your result. This brainstorm should be done before beginning the experiment so that arrangements can be made to account for the confounding factors before taking data. Sometimes a correction can be applied to a result after taking data, but this is inefficient an
for finding the same measurement, it is not essential that they may get the same results. There may arises a http://www.citycollegiate.com/chapter1bXI.htm difference between their measurements. This difference is referred to as an "ERROR". Types Of Error Errors can be divided into three categories: (1) Personal Error (2) Systematic Error (3) Random Error Personal Error www.citycollegiate.com An error comes into play because of faulty procedure adopted by by the observer is called "PERSONAL ERROR". Personal error comes into existence experimental error due to making an error in reading a scale. It is due to faulty procedure adopted by the person making measurement. Systematic Error The type of error arises due to defect in the measuring device is known as "SYSTEMATIC ERROR" Generally it is called "ZERO ERROR". it may be positive or negative error. Systematic error can be unavoidable experimental error removed by correcting measurement device. Random Error The error produced due to sudden change in experimental conditions is called "RANDOM ERROR". For example: During sudden change in temperature, change in humidity, fluctuation in potential difference(voltage). It is an accidental error and is beyond the control of the person making measurement. Atomic Mass www.citycollegiate.com Atomic mass is defined as : "The mass of one atom of the element compared with the mass of one atom of C12" Atomic mass is a ratio therefore it has no unit. Generally atoms mass is expressed in ATOMIC MASS UNIT(a.m.u). One atomic mass unit is equal to 1/12 of the mass of a C12 atom. Empirical Formula "Empirical Formula is that formula which expresses the relative number of each kind of atoms present in the molecule of a compound" OR "The formula of a compound which expresses the ratio in which atoms of different elements are combined in a molecule" Empirical formula only indicates atomic ratios but it does not indicate actual number of ato
