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