interpolation is a technique for
a) obtaining most likely missing links
b) finding relationship between two variables
c) comparing the two series
d) none of above
Ans) interpolation is a technique for
a) obtaining most likely missing links
Interpolation is a mathematical technique to estimate the values of unknown data points that fall in between existing, known data points. This process helps fill in the blanks. Technical traders use interpolation to understand how prices have behaved in the past, even when they do not have full information.
interpolation and extrapolation are same in the sense that a) both determine most likely estimateb) both result into the same value c) both are complementary to each other d) all the above
interpolation is not affected by a) sudden fluctuations b) irregular variations c) unforeseen events d) none of the above
estimation under interpolationa) is less accurate than extrapolation b) is an accurate as extrapolationc) is more accurate than extrapolationd) none of the above
interpolation means estimating a value which lies a) within the given range of arguments b) outside the given range of arguments c) outside the range of the independent variable d) none of the above
1. You have a dataset from a random sample of U.S. adults and are analyzing two variables measured as follows:Sex (0=male; 1=female) and Felony criminal record (0=no; 1=yes). Which statistic is most appropriate for describing the strength of the relationship between these two variables? Chi-square Phi-coefficient Goodman and Kruskal's gamma Yule's Q None of the above 2. A hypothesis test for the difference between two independent sample means assumes ____________. we have two samples that are independently selected we have...
Which of the following statements is (are) the most correct? A. Sensitivity study is a technique in which key variables are changed one at a time. B.

1. The Pearson’s correlation is used to test a relationship between two variables___________. A. if a non-linear relationship is tested. B. if a linear relationship is tested. C. if both variables are continuous (i.e., are measured on an interval or ratio scale). D. if both variables are measured on a nominal scale. E. A & D F. B & C 2. A researcher found a Pearson correlation of r = - 0.28 between self-reported stress level and intensity of physical...
