To take into account the loss in the cable, we just have to deduce the 3 dB loss from the 18 dBi gain and use a modified antenna gain of G = 15 dBi. In one click we find the electrical field strength E = 1.4 V/m, the magnetic field strength H = 3.7 mA/m and the power density S = 5.0 mW/m2.
Types of Data: Primary and Secondary data. There are many ways of classifying data. A common classification is based upon who collected the data. Primary data: Data collected by the investigator himself/ herself for a specific purpose. Examples: Data collected by a student for his/her thesis or research project. (In movies) The hero is directly told by the heroine that he is her âideal manâ.
Defining Primary Data in Market Research. Primary data is information that you collect specifically for the purpose of your research project. An advantage of primary data is that it is specifically tailored to your research needs.A disadvantage is that it is expensive to obtain.esson Summary. Primary data is information that you collect specifically for a particular research project. You need to determine your target population and the size and type of sample you will draw from the target population before you commence data collection.
