What are the two advantages of survey method in psychology?
Methods Of Enquiry In Psychology. Write two advantages of the survey methods. (i) Information can be gathered quickly and efficiently from thousands of persons. (ii) Since surveys can be conducted quickly, public opinions on new issues can be obtained almost as soon as the issue areas.
What are the disadvantages of Tacheometry?
Disadvantages of tacheometry:
- In a rough country, both horizontal and vertical measurements are tedious and chaining is inaccurate, hard, and slow.
- This method is usually the fastest and best for figure detection and typographic detailing.
What are the instrument used in theodolite survey?
theodolite, basic surveying instrument of unknown origin but going back to the 16th-century English mathematician Leonard Digges; it is used to measure horizontal and vertical angles. In its modern form it consists of a telescope mounted to swivel both horizontally and vertically.
What is theodolite used for?
The theodolite is most accurate instrument used mainly for measuring horizontal and vertical angles. It can also be used for locating points on a line, prolonging survey lines, finding difference in elevations, setting out grades, ranging curves etc. ADVERTISEMENTS: (2) Non transit.
Is theodolite a linear surveying method?
Which of the below is not a means of linear surveying methods? Explanation: Theodolite is an instrument used to measure angular readings. It is used in angular surveying. All other options are used to take linear measurements.
What is survey method in psychology?
A survey is a data collection tool used to gather information about individuals. Surveys are commonly used in psychology research to collect self-report data from study participants. A survey may focus on factual information about individuals, or it might aim to obtain the opinions of the survey takers.

What is the difference between theodolite and tacheometer?
The theodolite when works as a level instrument it is called a Tacheometer. The difference is level have no movement in vertical axis. Theodolite can move in vertical axis. If we want to measure the reduced level of a hill, it is very taught to do this by using level instrument.
Which instrument is used for tacheometry survey?
tacheometer
The instrument for tacheometry is the tacheometer. By means of it the horizontal distance is determined by optical or electronic (electro-optical) distance measurement, and the horizontal angle is determined numerically or graphically.
What is theodolite surveying instrument?
One of the important types of such surveying instruments is the Theodolite. Theodolite may be defined as the optical survey instrument that is used to measure the angles between the specified points both in the vertical and horizontal plane.
What is the classification of theodolite?
THEODOLITE SURVEYING. CLASSIFICATION OF THEODOLITES. A. Transit Theodolite: A theodolite is called a transit theodolite when its telescope can be transited i.e revolved through a complete revolution about its horizontal axis in the vertical plane, whereas in a- Non-Transit type, the telescope cannot be transited.
What is the method of transit of theodolite?
It can be done by means of plumb bob suspended from a small hook attached to the vertical axis of the theodolite. Transiting :- Transiting is also known as plunging or reversing.
What is temporary adjustment of theodolite?
Temporary adjustment of theodolite are following types. It is a process of setting up instrument over station marking by the help of plumb bob. Centering done by help of moving tripod leg without disturbing plump bob. We do leveling of theodolite instrument by the help of foot screw with reference to upper plate.
