Slide this ruler across the surface of plans, maps, and blueprints and read the measurement on the digital display in one of 111 different scales including inches, feet, yards, miles, centimeters, meters, kilometers, or a scale you define. A 1/32 division is equal to 2/64 divisions (Figure 4). For durability and accuracy, etched or scribed marks are usually preferable to surface coatings such as paints and inks. Graduations on the scale are up to : Some examples of variables that can be measured on a nominal scale include: 1. Understanding these differences is the key to getting the most appropriate research data. There are 2 PI radians in a circle. For example: A truck scale reads out its weight in 20/graduation. Using 1/16 Measurements Practice 1 Name Class Date Directions: For each set of measurements, add, subtract, or multiply them together as directed to get a total measurement. Another key difference in interval scale vs ratio scale is the levels of measurement that have been explained in this blog. 0000026153 00000 n EXAMPLE EXERCISE 2.1 Uncertainty in Measurement. Graduations can also be spaced at non-linear intervals, such as logarithmic, where the interval between them varies. Linear graduation of a scale occurs on a linear measuring device, such as a rule or measuring tape using units such as inches or millimetres. 6 Ft. Long x 1-1/4 Inch Wide, 1/16 Inch Graduation, Silver, Mylar Adhesive Tape Measure Reads Right to Left, Horizontal Scale MSC# 67754804 Made in USA In Stock Political Preference: Republican, Democrat, Independent 6. Step 3: Estimate the uncertain digit and obtain a reading: Estimate the distance that the meniscus lies between the two graduations as a decimal fraction and multiply by the scale … 9 CGAP (2011) Reaching the Poorest: Lessons from … As nouns the difference between scale and graduation is that scale is an ordered numerical sequence used for measurement or scale can be part of an overlapping arrangement of many small, flat and hard pieces of keratin covering the skin of an animal, particularly a fish or reptile or scale can be a device to measure mass or weight while graduation is the action or process of graduating and receiving a … Each group has attributes distinctly different from the other. 0000104028 00000 n For example, if we want to categorize male and female respondents, we could use a number of 1 for male, and 2 for female. There can also be non-uniform graduations such as logarithmic or other scales such as seen on circular slide rules and graduated cylinders. 49 0 obj << /Linearized 1 /O 51 /H [ 1194 258 ] /L 391726 /E 129067 /N 7 /T 390628 >> endobj xref 49 38 0000000016 00000 n 0000002253 00000 n 0000001194 00000 n In the case of stamping, the master has the precision built into itself and the stamped device is as accurate as the stamping process allows. A nominal variable is one in which values serve only as labels, even if those values are numbers. 0.1% of full scale for test gauges: 0.5 to 1% of full scale for industrial gauges; 1 to 3% of full scale for utility … trailer << /Size 87 /Info 48 0 R /Root 50 0 R /Prev 390618 /ID[] >> startxref 0 %%EOF 50 0 obj << /Type /Catalog /Pages 37 0 R /JT 47 0 R /PageLabels 36 0 R >> endobj 85 0 obj << /S 72 /L 165 /Filter /FlateDecode /Length 86 0 R >> stream A graduation is a line or number on a container or measuring instrument which marks a particular measurement....medicine bottles with graduations on them. Similarly, molding of plastic can be as precise as the mold process. The nominal or categorical statistical scale of measurement is used to measure those variables that can be broken down into groups. 0000114907 00000 n 0000003800 00000 n %PDF-1.3 %���� I cant figure out if it is nominal , ordinal or interval? For accuracy the volume on graduated cylinders is depicted on scales with 3 significant digits: 100mL cylinders have 1ml grading divisions while 10mL cylinders have 0.1 mL grading divisions. So a steel rule that is graduated to 1/64" is accurate to about 0.015". There are graduation marks below the meniscus, and each graduation represents 0.5 mL, so the certain digits of the reading are 21 mL. 0000002956 00000 n It is defined as a quantitative measurement scale in which the difference between the two variables is meaningful. Which measurements are consistent with the metric rulers shown in Figure 2.2? 0000105873 00000 n Minor Graduation: Specify the minor graduation required for the pressure gauge: Nominal Accuracy: Specify the expected accuracy performance of gauge. 0000001956 00000 n Class A has double the accuracy of class B. Cylinders can have single or double scales. 4. Place you live:City, suburbs, rural Variables that can be measured on a n… The reading on a Vernier caliper is an combination of the value obtained from the main scale and the value evident on the moving Vernier scale. They are used to measure interior and exterior dimensions such as rooms, walls, doors, windows, and fire protection system details. Answers must be in whole number and/or fraction form. McMaster-Carr is the complete source for your plant with over 595,000 products. In other words, we can put them in any order and it wouldn't matter. [1] Later developments in devices such as dividing engines allowed the process to be automated with greater precision. 0000002005 00000 n �5�����WJ0Y&�Ff���K'zbp�X�5���=4����d�rs�LF�a�G. 0000003175 00000 n H�b```�Ul�B� b�1G�#K ��l�4Nǀ�l��3h\� V�bu~�g,w�00057laa��whߠ}@�!��a����S�oҤ�L�S��&-�_"�x�۶��iG� �1��e�4{ �z# endstream endobj 86 0 obj 146 endobj 51 0 obj << /Type /Page /Parent 37 0 R /Resources 52 0 R /Contents 62 0 R /MediaBox [ 0 0 612 792 ] /CropBox [ 0 0 612 792 ] /Rotate 0 >> endobj 52 0 obj << /ProcSet [ /PDF /Text /ImageC /ImageI ] /Font << /TT2 61 0 R /TT4 57 0 R /TT6 63 0 R /TT8 66 0 R >> /XObject << /Im1 77 0 R /Im2 78 0 R /Im3 79 0 R /Im4 80 0 R /Im5 81 0 R /Im6 82 0 R /Im7 83 0 R /Im8 84 0 R >> /ExtGState << /GS1 70 0 R >> /ColorSpace << /Cs6 55 0 R /Cs8 56 0 R /Cs9 53 0 R /Cs10 60 0 R /Cs11 59 0 R >> >> endobj 53 0 obj [ /Indexed 55 0 R 255 75 0 R ] endobj 54 0 obj << /Type /FontDescriptor /Ascent 938 /CapHeight 0 /Descent -222 /Flags 32 /FontBBox [ -86 -262 1082 943 ] /FontName /NKLKNI+TrebuchetMS /ItalicAngle 0 /StemV 0 /FontFile2 67 0 R >> endobj 55 0 obj [ /ICCBased 72 0 R ] endobj 56 0 obj [ /Indexed 55 0 R 255 74 0 R ] endobj 57 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 190 /Widths [ 301 0 325 0 0 0 706 0 367 367 0 524 367 367 367 524 524 524 524 524 524 524 524 524 524 0 0 0 0 0 0 367 0 590 566 598 613 536 525 676 654 278 0 576 506 709 638 0 558 0 582 481 581 648 587 852 0 570 0 0 0 0 0 0 0 525 557 495 557 545 370 502 546 285 367 504 295 830 546 537 557 557 389 405 396 546 490 744 501 493 475 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 367 524 524 0 367 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 814 814 ] /Encoding /WinAnsiEncoding /BaseFont /NKLKNI+TrebuchetMS /FontDescriptor 54 0 R >> endobj 58 0 obj << /Type /FontDescriptor /Ascent 938 /CapHeight 0 /Descent -222 /Flags 96 /FontBBox [ -110 -258 1108 946 ] /FontName /NKLKLH+TrebuchetMS,Italic /ItalicAngle -15 /StemV 0 /FontFile2 69 0 R >> endobj 59 0 obj [ /Indexed 55 0 R 255 68 0 R ] endobj 60 0 obj [ /Indexed 55 0 R 255 71 0 R ] endobj 61 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 169 /Widths [ 301 0 0 0 0 0 0 0 0 0 0 0 0 0 367 0 524 0 524 0 0 0 0 0 0 524 0 0 0 0 0 0 0 0 566 598 0 0 0 0 0 0 0 0 506 761 0 0 543 0 0 481 0 0 0 0 0 0 0 0 0 0 0 0 0 525 557 460 0 537 0 502 557 307 0 0 320 830 546 537 557 0 417 405 420 0 0 0 0 493 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 713 ] /Encoding /WinAnsiEncoding /BaseFont /NKLKLH+TrebuchetMS,Italic /FontDescriptor 58 0 R >> endobj 62 0 obj << /Length 2135 /Filter /FlateDecode >> stream The Four Major Statistical Scales of Measurement 1.
