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