ASSIGNMENT Date: 07TH feb-2011 LAST DATE OF SUBMISSION: 14TH Feb-2012.
Each assignment are equal in weightage and compulasary ,those who are failed to submit before dead line will Get Zero Marks in Internal .
Q1) Explain the term ‘statistical analysis’,’ Arithmetic mean’,’ Average deviation’, ‘Standard deviation ‘ and variance with suitable example.
Q2) Explain in detail ‘classification of standards’, what are the standard s for mass, length, time, volume and frequency?
Q3) Explain in detail ‘classification of error ‘with suitable examples and remedies for them.
Q4) Explain the Accuracy and precision in detail and how they differ from each other?
Q5) what is the limiting error?
Prove that Aa=A (1±e) where Aa =the actual value of quantity As=Normal or specified
value of the quantity and ex=relative limiting errors.
Q6) Systematic errors are classified as Instrumental error, environmental error and
Observational error. Explain briefly, what are the causes of these errors .suggest
Corrective measures to reduce these errors.
Q7) what is histogram .explain use of Gaussian curve.
Q8) State the difference between fundamental and derived quantity with the help examples.
Q9) The resistive load the following rating r1=40±5%,r2=50±5%,r3=80±5% i) determine the magnitude and limiting error in ohm in percent of the resistance of these resistances connected parallel.
Q10) Set of independent measurement of voltages are recorded as 101.2, 101.4.101.7,101.3, 101.3, 101.2, 101.0, 101.3, 101.5, and 101.1.
