15s - Q2
Two types of estimation are...
biased and unbiased
type I and type II
point estimation and interval estimation
one sided and two sided
15s - Q3
A formula or rule used for estimating the parameter is called
estimation
estimate
interval estimate
estimator
15s - Q4
A value of an estimator is called
variable
estimation
constant
estimate
15s - Q5
The process of using sample data to estimate the values of unknown population parameter is called
estimation
estimate
estimator
interval estimation
15s - Q6
The process of making estimates about the population parameter from a sample is called
statistical decision
statistical hypothesis
statistical independence
statistical inference
15s - Q7
Statistical inference has two branches, namely
point estimator and interval estimator
estimation of parameter and testing of hypothesis
biased estimator and unbiased estimator
level of confidence and degree of freedom
15s - Q8
A single value used to estimate a population values is called
level of confidence
degree of freedom
interval estimate
point estimate
15s - Q9
An interval calculated from the sample data and is likely to contain the value of parameter with some probability is called
interval estimate
level of significance
point estimate
confidence interval
15s - Q10
A range of values within which the population parameter is expected to occur is called
level of significance
confidence coefficient
confidence limits
confidence interval
15s - Q11
The end points of a confidence interval are called
parameters
confidence limits
error of estimation
confidence coefficient
15s - Q12
If the mean of the estimator is not equal to the population parameter, the estimator is said to be
biased
positively biased
unbiased
negatively biased
15s - Q13
Interval estimate is associate with
probability
non-probability
range of values
number of parameters
15s - Q14
The point estimator of population mean is
sample standard deviation
sample mean
sample variance
sample size
15s - Q15
If level of confidence is increased, the width of a confidence interval is
same
increased
decreased
constant
