0 d = 145 mi n question 2. an object moves along the grid through points a, b, c, d, e, and f as shown below. the side of square tiles measures 0.5 km. a) calculate the distance covered by the moving object. b) find the magnitude of the displacement of the object. solution...
Both descriptive and inferential statistics are types of statistical analysis used to describe and analyze data. Here are the main differences between them:Definition Descriptive statistics use measures like mean, median, mode, standard deviation, variance, and range to summarize and describe a data ...
stretched vertically by a factor of c if c > 1. shrinkage of graphs of functions the graph of ch(x) is the graph of h(x) shrunk vertically by a factor of c if 0 < c < 1. theorem for sum of interior angles of n-sided polygon the sum of the measures of a n-sided polygon's...
box and whisker plot . quartiles are the values that divide a list of numerical data into three quarters. the middle part of the three quarters measures the central point of distribution and shows the data which are near to the central point. the lower part of the quarters indicates just ...
For instance, ISO 2631 Clause 6.3 begins with: “In cases where the basic evaluation method may underestimate the effects of vibration (high crest factors occasional shocks, transient vibration), one of the alternative measures described below should also be determined—the running r.m.s. or the...
Thus, the simplified calculation formulas as well as the simulation algorithms based on the formulas can provide a valuable reference to entropy optimization from a new perspective, supplementing the existing measures such as mean and variance to extend the applications of LR fuzzy intervals. Table ...

However, the standard deviation is not free of limitations which include arguments like the difficulty in calculations and extreme observations can tend to affect it’s value to a large extent. But, considering all the pros and cons, it still wins the race among all measures of dispersion ...
The correlated t-test, or paired t-test, is a dependent type of test and is performed when the samples consist ofmatched pairsof similar units, or when there are cases of repeated measures. For example, there may be instances where the same patients are repeatedly tested before and after ...
