The level of measurement refers to the relationship among the values that are assigned to the attributes for a variable. Begin with the idea of the variable, in this example "party affiliation." That variable has a number of attributes. Let's assume that in this particular election context the only relevant attributes are "republican", "democrat", and "independent". For purposes of analyzing the results of this variable, we arbitrarily assign the values 1, 2 and 3 to the three attributes. The level of measurement describes the relationship among these three values. In this case, we simply are using the numbers as shorter placeholders for the lengthier text terms.

How many significant values does 1089 have?
It has 4 significant digits but only one value.
What determines Frequency of an AC signal?
A protective relay determines frequency of an AC signal of an electric power system. The protective relay includes a circuit measuring the AC signal period between zero crossings to provide a measured period value. A microprocessor includes a random access memory having a five-element array, which collects five consecutive values of the measured period values. A microprocessor routine chooses a median from the measured period values and generally determines the frequency based upon the median. The median is ignored and the previously determined line cycle period is adjusted to determine the new line cycle period if: an absolute value of a difference between a last value of the measured period values and a previously determined line cycle period is not less than a predetermined value; and the last value of the measured period values is within the limits of the array. <Prof Dae_Pwa>
measured value 28.7053cm which has six significant figures round the measurement to four significant figures?
28.71
What number of significant figure is the measured value 0.003 20 g is?
23
How a measured value is reported in terms of known and estimated digits?
Significant Figure.
What differecne between the accuracy and precision?
Accuracy is how close the value that is measured to a true or standard value. While precision is referred as the degree of nearness of the measured values to one another in a repeated same value.
How does one measure the surface roughness of an object?
A roughness value can either be calculated or measured on a profile or on a surface. The profile roughness parameter are more common. The area roughness parameters give more significant values.
Would you expect the energy content values that you measured to be close to the value listed in dietary books why?
yes definetly why not/
How do you measured values?
there r many ways to measure value, rarity, weight, how hard it was to make, who made it, and how old it is.
What are the number of significant figures in the measured value 0.320 g?
0.320g has three significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
Why are measured values of resistors different from the stated values?
1: Resistors are manufactured with different tolerances, ie they're allowed to be both a bit above as well as below the target value. 2: If you're using a simple multimeter there's no telling how close the measured value is to the real value anyhow, once that you get down to the decimal places.
How do I tell if a T-test is significant with an alpha of 05 and if you already have significance values?
If you already have your p-value, compare it with 0.05. If the p-value is less than an alpha of 0.05, the t-test is significant. If it is above 0.05, the t-test is not significant.
