For skewed data displays, the median is often a better esitmate of the center of distribution than the mean, but
bazaltina [42]

For skewed data displays, the median is often a better estimate of the center of distribution than the mean because the former is unaffected by large numbers.

<h3>What is mean?</h3>

Mean refers to the average of set of two or more numbers.

Mean of a set having 'n'  numbers = \frac{Sum Of 'n' Numbers}{n}

<h3>What is median?</h3>

Median refers to the middle-most value of a list of numbers, arranged either in ascending or descending order.

Median = \left \{ {{\frac{n}{2}^{th}  term, if n = even } \atop( (\frac{n-1}{2}+\frac{n+1}{2})/2)^{th} term, if n = odd   }} \right.

Now,

  • Since it takes the average of all the values in the data set, the mean is the most widely used measure of central tendency.
  • Because it is unaffected by exceptionally big numbers, the median performs better than the mean when analyzing data from skewed distributions.

Hence, For skewed data displays, the median is often a better estimate of the center of distribution than the mean.

What is the best first step for solving the given system using substitution while avoiding fractions? =9x+4x=10 -9x+3y=3
aivan3 [116]

Answer:

  Solve for y in the second equation

Step-by-step explanation:

We assume your system is ...

  • -9x +4y = 10
  • -9x +3y = 3

Dividing <em>the </em><em>second equation</em> by 3 gives ...

  -3x +y = 1

so an expression for y without fractions can be found by <em>solving for y</em>, that is, by adding 3x:

  y = 3x +1

_____

<em>Comment on alternate solution</em>

We'd be tempted to solve the first equation for -9x and substitute for that.

  -9x = 10 -4y

  (10 -4y) +3y = 3 . . . . . substitute for -9x

  -y = -7 . . . . . . . . . . . . . simplify, subtract 10

  y = 7 . . . . . . . . . . . . . . multiply by -1
