consists of the collection, organization, presentation and analysis of data.

consists of higher degree of analysis, interpretation and inferences.

is a characteristic of a population on sample which makes one different from the other.

refers to a large collection of objects, persons, or things.

is a part of a population that has the same characteristics of the given population.

are data that can be placed into categories according to their characteristics or attributes.

are data which are numerical in nature. These data can be ordered or ranked.

assumes values that can be counted and their values are represented by counting numbers only.

is one which can assume all values between any two Specific values or intervals. The values are obtained through measurement.

is affected or influenced by another variable.

is the staggered food supply and the dependent variable is the secluded patient.

is a value or measure obtained from a population. If one uses the mean, median, mode & standard deviation to differentiate the achievement of a class from another class, then these measures are parameters.

is any value or measurement obtained from a sample. It is an estimate of the parameter.

classifies data in non-overlapping scale. This scale distinguishes one object from another object for identifying purposes only.

classifies data into some Specified order or rank.

Specifies the precise difference between or among the values of ranks.

has the same characteristics as the interval level; the only difference is that the ratio level always starts from zero.

The researcher makes direct and personal contact with the interviewee. The researcher gathers data by asking the interviewee Series of questions.

The researcher distributes the questionnaires either personally or by mail and collects them by the same process. The researcher can save a lot of time and energy.

This method of collecting data is governed by our existing laws.

is used to find out the cause and effect relationship of certain phenomena under controlled conditions.

The researcher may observe subjects individually or group of individuals to obtain data and information related to the objectives of the investigation.

The researcher may ask or invite individuals to send text opinions on certain issues or Send in their choices on their brand preferences on a particular product using their cellphones.

is also known as raffle. Each member of the population is numbered on a piece of paper. the pieces of paper shall be identical and rolled evenly. they are placed in a lottery box and shaken very well the desired number of samples are drawn. one after the other, with eyes away from it.

is used to draw the numbers for the sample. Suppose in a class of 30 students, 5 will be Selected at random and transferred to another class. Then, if the first 2-digit number of the random numbers is 26, the number 26 of the class is the first sample. the process is continued until the 5th number is chosen.

This is done by numbering each element of the population.

We obtain samples by dividing the population into strata(groups). If the desired sample is 50 and there are 10 strata, then we obtain the sample proportionately from each stratum. The bigger the strata. the more number of Samples are taken.

This is sometimes called AREA SAMPLING because it is used for a large population. We select members of the sample by area; then we select each area by lottery sampling.

We use combinations of Several random sampling techniques in getting the sample from a very large population. This is done by dividing the whole population by area, and then each area into strata. Thereafter, from each stratum, we get the sample by using the simple random sampling technique.

This is used because it is Convenient to the researcher.

the researcher uses the proportions of different strata; and from the strata, Selections are done using quota.

The researcher gets his sample from the respondents purposely elated or close to him.
