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