Observation frequency refers to how often data is collected through direct observation of behaviors or events, typically in a specific setting or context. In contrast, survey frequency pertains to how often surveys are administered to gather responses from participants about their opinions, behaviors, or experiences. While observation focuses on real-time data collection, survey frequency may involve periodic or one-time assessments, often relying on self-reported information. Both methods serve different purposes and can provide complementary insights in research.
Through observation, survey, or secondary data
A Census is the type of survey for a complete population. A Sample Survey is only a portion of the population which is used to make predictions on the representation of the actual population.
Blocking is more for experimental design while strata is for survey sampling.
Biased- (Not random) Unbiased-(Random) Example: (ubbiased) Woman takes random people to take a survey.
The main difference is that the way of selecting a sample Random sample purely on randomly selected sample,in random sample every objective has a an equal chance to get into sample but it may follow heterogeneous,to over come this problem we can use stratified Random Sample Here the difference is that random sample may follow heterogeneity and Stratified follows homogeneity
difference between survey and experiment
Market survey can be done using different techniques such as preparing questionnaires,direct contact with customers whereas in market observation the needs and wants of the customers are simply done by observing as to what they buy or what do they prefer
The words, observation and survey, each have several different meanings, but they also have a meaning that is similar. One definition of observation and survey is the act of observing, looking or seeing. Another definition for observation is the act of noticing something. Another definition for survey is the act of making an inspection.
differentiate between field experiment and survey and advantages
Survey research involves collecting data through questioning individuals, typically through interviews or questionnaires, to gather information about their attitudes, beliefs, or behaviors. Observation research involves studying and recording behaviors or phenomena in their natural setting without intervening or questioning participants. Observation research relies on directly observing and recording behavior, while survey research relies on self-report data collected through questioning.
Face left observation(In theodolite survey):If the face of the vertical circle is to the left of the observer, the observation of the angle is known as Face left observationFace Right observation(In theodolite survey):If the face of the vertical circle is to te right of the observer, the observation of the angle is known as Face right observation

Plain surveying means the survey in which earth surface is considered as to be flat or plain i.e. its curvature is ignored. Geodetic survey is the survey in which curvature of the earth is taken into count and then surveying is done.

An audit specifically examines finances, whereas a survey could be about anything, such as people's opinions regarding potato chips.
A sample survey is asked of a limited group of people, while a census is conducted in an attempted to get an answer from all people in a geographical area.
