There are three terms that are commonly used to determine the size of an object related to measurement in a broad sense, ie the measurement, interpretation and forecasting.<\/span> Do you know the difference between these three terms?<\/span><\/p>\n

Understanding third term measurements as shown below, namely:<\/span>
\n 1. Measurement<\/strong><\/span>
\n Measurement is the observations made by direct measurement using a specific measuring instrument and was made to all the objects observed.<\/span><\/p>\n

2. interpretation<\/strong><\/span>
\n The interpretation is the observation made by using a specific measuring instrument but only partially carried out on the object observed.<\/span> Object observed is called population was part of the observed object is called a sample (sample).<\/span> If the population is trees in the forest, then sample a collection of trees found in the plots (PU).<\/span> The plot can be circular, square, rectangular or track.<\/span> The interpretation is done in several ways, including through:<\/span>
\n a.<\/span> Method number form.<\/span>
\n b.<\/span> Rates \/ local table.<\/span>
\n c.<\/span> Table stands.<\/span>
\n d.<\/span> Table of results.<\/span>
\n e.<\/span> Table class form.<\/span><\/p>\n

3. Forecasting<\/strong><\/span>
\n Forecasting is an activity to determine the value of an object by attempting to measure the conditions that will come with the data obtained in the past by a certain time.<\/span> Forecasting is commonly used in the field of meteorology and geophysics as well as the macro economy.<\/span><\/p>\n

Of the three terms mentioned above, measurement is the topic of discussion in the textbook teaching materials this student.<\/span> In the measurement usually always encountered an error (bias).<\/span>
\n Based on the source, the error is divided into two, namely:<\/span>
\n a.<\/strong><\/span> sampling Error<\/strong><\/span>
\n Sampling error is an error that arises due to the sample size, sample size, and shape of the sample and sampling methods used.<\/span> Sampling error often occurs in the interpretation and forecasting.<\/span>
\n b.<\/strong><\/span> Non-sampling errors<\/strong><\/span>
\n Non-sampling error is an error caused by its own measurement factors, among others:<\/span><\/p>\n
