                    1.  Define the term blunder and error.
                    2.  Write the difference between blunder and error.
                    3.  What  are  the  basic  difference  between  systematic  error  and  an  accidental
                  error?
                    4.  Indicate  the  type  of  error  or  mistake-  the  following  would  cause  as  A
                  (Accidental), S (Systematic) or B (Blunder):
                            a) Swinging plumb bob while taping
                            b) Using a repaired tape
                              c) Aiming the theodolite at the wrong point
                              d) Recopying field data
                              e) Reading a 9 to a 6
                              f) Surveying with a level that is not leveled
                              g) Having too long a sight distance between the level and the level rod
                    5.  Convert the following angles to decimal degree form:
                               0
                              a) 35 20’(use two decimal places)
                                 0
                              b) 129 35’15”(use four decimal places)
                    6.  Convert the following angles to degree, minutes, and seconds:
                                   0
                               a) 45.75 (to the nearest minute)
                                       0
                               b) 123.1234 (to the nearest second)
                                                    0
                                                                                             0
                                                                     0
                    7.  What  is  the  sum  of  45 35’45”  and  65 50’22”?  Subtract  45 52’35”  from
                      0
                  107 32’00”.
                    8.  With reference to the above problem, what would the maximum anticipated
                  error be for a survey that was three times as long, if the same precision was used?
                    9.  A group of surveying students measure a distance twice, obtaining 67.455
                  and 67.350 m. What is the relative accuracy of the measurements?
