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