Describe a data set where the mean would be the most appropriate measure of center. Describe a data set where the mean is not th

Leona [35]

1. You should use the median to describe the measure of the center of a data set when an outlier is present in a data set.

Having an outlier will skew the mean of the data.

This means it will adjust the average to be smaller or greater than what the actual numbers are showing.

The median should be used as the measure of center in these circumstances.

2) Using a box plot, you can find the range and interquartile range.

<h3>What is the range?</h3>

The range is the distance from the smallest number to the largest. The interquartile range is the distance from the first quartile to the third quartile.

All these values are found on a box plot.

3)The best measure of spread to describe symmetrical data sets is the mean absolute deviation.

This tells us how far on average the numbers are spread out from the mean.

4) See the answer given in 1 for the explanation. An example would be a student who scores 8, 9, 10, 9, 10, and 2 on 6 quizzes.

The mean would be an average of 8, which is not a good number to represent the score this student normally gets.

The median of 9 is a better number to show how this student normally performs.

prove that if f is integrable on [a,b] and c is an element of [a,b], then changing the value of f at c does not change the fact

Neko [114]

Answer with Step-by-step explanation:

We are given that if f is integrable on [a,b].

c is an element which lie in the interval [a,b]

We have to prove that when we change the value of f at c then the value of f does not change on interval [a,b].

We know that limit property of an integral

$\int_{a}^{b}f dt=\int_{a}^{c}fdt+\int_{c}^{b} fdt$

$\int_{a}^{b} fdt=f(b)-f(a)$ ....(Equation I)

Using above property of integral then we get

$\int_{a}^{b}fdt=\int_{a}^{c}fdt+\int_{c}^{b} fdt$ ......(Equation II)

Substitute equation I and equation II are equal

Then we get

$\int_{a}^{b}fdt= f(c)-f(a)+{f(b)-f(c)}$

$\int_{a}^{b}fdt=f(c)-f(a)+f(b)-f(c)=f(b)-f(a)$

$\int_{a}^{c}fdt+\int_{c}^{b}fdt=f(b)-f(a)$

Therefore, $\int_{a}^{b}fdt=\int_{a}^{c}fdt+\int_{c}^{b}fdt$ .

Hence, the value of function does not change after changing the value of function at c.
