Let x be the median of data: 33, 42, 28, 49, 32, 37, 52, 57, 35, 41. If 32 is replaced by 36 and 41 by 63, then the median of the data, so obtained, is y. What is the value of (x + y)? मान लीजिये कि x इन आंकड़...
it is necessary to write down all the values in the data set in increasing order. The median formula differs depending on the number of observations there are in the data set and whether the number of observations they odd or even. The following...
What is the median score achieved by a student who recorded the following scores on 10 math quizzes? Data: 68, 55, 70, 62, 71, 58, 81, 82, 63, 73. Your test scores in one class are 84 and 88. What possible scores can you earn on t...
What is the value of R^2? How do you know the symmetry of data from mean and median? Predict the value of y for x = 50. a) 278.836 b) 451.396 c) 192.556 d) not meaningful Identify or define the term: Between-groups sum of squares ...
What is Algebra? Algebra helps solve the mathematical equations and allows to derive unknown quantities, like the bank interest, proportions, percentages. We can use the variables in the algebra to represent the unknown quantities that are coupled in such a way as to rewrite the equations. ...
By observing the different activities in our day to day life, give two instances where collecting data is necessary. What is the difference between statistics and probability? What is ‘mean’? What is ‘median’? What is ‘mode’?
median LSAT score or GPA at a law school is not the minimum number required to get in. On the contrary, this figure is the midpoint between the highest and lowest credentials among incoming students, meaning it is possible to get into a school with a score or GPA that is below...
If we are given a frequency table, to find the median, what we do first is sum the frequencies to determine the number of observations. If the sum, say n, is odd, then the median is located at the (n+12) th position. If it is even,...
A Histogram is useful in displaying a large amount of data in a more understandable way, which is easy to visualize. It also captures the frequency density of each class interval. We can determine the median and the distribution of data from a Histogram. Also, the skewness of the distributio...
Who Is Losing Ground? However, the data also suggests that middle-class families continue to lose financial ground to upper-income families. While the median income of the upper class increased 9% over the past decade, the median income of the middle and lower classes only increased by about...
