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