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