3. Sampling error is a statistical error that occurs when an analyst does not select a sample that represents the entire population of data. T he result found in sample thus do not represent the results that would be obtained from the entire population . Sampling error can be reduced by randomizing sample selection and increasing the number of observations INTRODUCTION

4. . Sampling error refers to differences between the sample and the population that exist only because of the observations that happened to be selected for the sample Increasing the sample size will reduce this type of error Sampling error sample sample Sampling error population population MEANING

5. Biased Sample error Unbiased sample error TYPES

6. N onprobability sampling is a method of sampling wherein, it is not know that which individual from the population will be selected as a sample. probability sampling is a sampling technique in which the subject of the population get an equal opportunity to be selected as a representative sample. Probability Sampling NonProbability Sampling PROBABILITY

9. Sampling is the procedure a researcher uses to gather people, places or things to study . The representative proportion of the population is called a sample . Population refers to the large group from which the sample is taken . Probability and Non-probability sampling are two strategies of sampling . Sampling and Non-sampling error may occurs due to biased sample and wrong measurement . CONCLUION
