box-and-whisker plot
y = f(x) = 75x has a slope of 75 (steep) and an x,y intercept of (0,0). Graph it as a very steep, straight line passing through the origin from lower left to upper right.
The answer is B.
The cumulative frequency curve is shaped like an S. The lower quartile is 1/4 the way up on the cumulative frequency axis. The upper quartile is 3/4 the way up on the cumulative frequency axis The inter-quartile range is the upper quartile minus the lower quartile as plotted on the horizontal axis. Further details can be found in a higher level maths text book.
Generally the x-axis is displayed on a 2-dimensional Cartesian Coordinate system running horizontally (left to right - for negative to positive values of x) In a 3-D graph, the x-axis is usually shown running diagonally from upper right to lower left (for negative to positive values of x) . In a 3-D graph, the y-axis is the one running horizontally and the z-axis is vertical.
You cannot list them: unless the inequality is trivial, since there are infinitely many real numbers in any range. You need toidentify the lower bound;determine whether or not the lower bound is included (
No.
Yes
The lower quartile is the second smallest and the upper quartile is the fourth smallest (second largest).
See related link. Upper and lower quartiles are the 75 and 25% percentile measures.
The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. Quartiles divide a rank-ordered data set into four equal parts.
The interquartile range is well known as a measure of statistical dispersion. It is equal to difference between upper and lower quartiles. The quartiles is a type of quantile.
There is no need to lose your rag!It is the inter-quartile range.
The upper quartile is the value such that a quarter of the data are greater than that value. Similarly, the lower quartile is the value such that a quarter of the data are lower than that value.
Yes. Usually the value of the lower quantile, median, and upper quantile are in ascending order, how if for the particular set of data, if all values are the same, then these three measures can be the same.
The upper quartile of a set of data is a value such that a quarter of the observations are greater than that value. The lower quartile is similarly defined as the value such that a quarter of the observations are less than that value.
It is marked by the minimum, and maximum, the median, as well as the lower and upper quartiles. It also shows the skewness of the data.
To find the inner quartiles (Q1 and Q3), first arrange your data in ascending order. Q1 is the median of the lower half of the data, and Q3 is the median of the upper half. The inner quartiles divide the data into four equal parts. The outer quartiles also known as the minimum and maximum values, are the smallest and largest values in the data set.
