Selected Random Entire Fixed None In Statistics, __________ Classification includes data according to the time period in which the items under consideration occurred Alphabetical Geographical Chronological Topological None By the definition of randomness, each ____________ has the same chance of being considered Random entity Probable entity Observed entity Possible entity None The method of sampling, in which the choice of sample items depends exclusively on the judge of investigator is termed as Quota sampling Convenience sampling Judgmental sampling Systematic sampling None The ________ process would be required to ensure that the data is complete and as required. Ordering Tabulation Analysis Editing None Data is the simply the numerical results of any scientific Researches Analysis Observation Measurement None If the average of a series of values is 10 and their variance is 4 then coefficient of variation is 40 % 20% 2.5 % 10 % None The sum of the deviations about the mean is always: Range Always zero Total standard deviation Can’t say None The basic objective of a sample is to draw _______about the population from which such sample is drawn Characteristic Parameters Conclusion Inferences None A median of series of numerical values is The most commonly encountered values in series A measure of eccentricity of the series A value for which half of values are lower and half of values are higher The value exactly located midway between minimum and maximum of the series None Sampling is the simple process of learning about the _______on the basis of sample drawn from it. Group Population Census Area None The mean of a distribution is 23, the median is 24, and the mode is 25.5. It is most likely that this distribution is: Positively skewed Asymptotic Symmetric Negatively skewed None The larger the size of the population, the _________ should be the sample size. Smaller Larger Fixed Accurate None A perfect random number table would be one in which every digit has been entered ________. Chronologically Arbitrarily Sequentially Randomly None A chance variation in an observational process is Measurement error Dispersion/variability Random error Instrument error None A parameter is a measure which is computed from Population data Sample data Test statistics None of these None Which of the following divides a group of data into four subgroups? Median Percentiles Quartiles Variance None If series consist of 41 numbers then for finding the median, we ordered the series in ascending and we use The 20th value of order series The average of 21st and 22nd values The average of 20th and 21st values The 21st value of order series None According to the empirical rule, approximately what percent of the data should lie within μ±σ? 95 % 99.7 % 68 % Can’t say None Both sampling and non-sampling error must be reduced to minimum in order to get representative a sample of the _________as possible. Universe Population Group Region None The stages of malignant disease (Cancer) is recorded using symbol 0, I, II, III, IV. We say that the scale used is Numerical Alphanumeric Ordinal Nominal None Fundamental statistical Indicators are Mean and Variance Mean Variance Median None A population, in statistical term, is the totality of things under consideration. It is the collection of all values of the_________that is under study.
