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