Positive Skewness If the given distribution is shifted to the left and with its tail on the right side, it is a positively skewed distribution. It is ALSO called the right-skewed distribution.

Negative Skewness If the given distribution is shifted to the right and with its tail on the left side, it is a negatively skewed distribution. It is also called a left-skewed distribution. The skewness value of any distribution showing a negative skew is always less than zero. The skewness of the given distribution is on the left; hence, the mean value is less than the median and moves towards the left, and the mode occurs at the highest frequency of the distribution.

3.

For a set of 10 observations,∑x = 452, ∑x² = 24270 and mode = 43.7 Find Pearson's coefficient of skewness.

Answer»

$\begin{gathered}\begin{gathered}\bf \:Given-\begin{cases} &\sf{number \: of \: observations \: (n) = 10} \\ &\sf{ \sum \: x = 452}\\ &\sf{ \sum \: {x}^{2} = 24270 }\\ &\sf{<klux>MODE</klux> = 43.7} \end{cases}\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\bf \: To \: Find - \begin{cases} &\sf{Coefficient \: of \: skewness \: (S_k)}\end{cases}\end{gathered}\end{gathered}$

$\begin{gathered}\Large{\bold{{\underline{Formula \: Used - }}}} \end{gathered}$

$\underline{\boxed{ \sf \: Coefficient \: of \: skewness (S_k)= \dfrac{Mean - Mode}{Standard \: Deviation}}}$

$\large\underline{\sf{Solution-}}$

We know,

↝ Mean of data is given by

$\rm :\longmapsto\:Mean( \overline{x})= \dfrac{\: \displaystyle\sum_{i=1}^{n}{x _i}}{n}$

$\rm :\longmapsto\:Mean(\overline{x}) \: = \: \dfrac{\: \displaystyle\sum_{i=1}^{10}x_i}{10}$

$\rm :\longmapsto\:Mean \: ( \overline{x}) = \dfrac{452}{10} = 45.2 - - - (1)$

Now,

↝ We know that

↝ Standard deviation of given data is given by

$\rm :\longmapsto\:Standard Deviation \: (\sigma) = \sqrt{\dfrac{\: \displaystyle\sum_{i=1}^{n} {(x_i)}^{2} }{n} - {\bigg(\overline{x} \bigg) }^{2} }$

$\rm :\longmapsto\:Standard Deviation \: (\sigma) = \sqrt{\dfrac{24270}{10} - {(45.2)}^{2} }$

$\rm :\longmapsto\:Standard Deviation \: (\sigma) = \sqrt{2427 - 2043.04}$

$\rm :\longmapsto\:Standard Deviation \: (\sigma) = \sqrt{383.96}$

$\rm :\longmapsto\:Standard Deviation \: (\sigma) = 19.59 \: (approimately)$

Now,

↝ we have

$\begin{gathered}\begin{gathered}\bf \: \: \: \: \: \: \: \: \: \bull \: \: \: \:\begin{cases} &\sf{Mean = 45.2} \\ &\sf{Mode = 43.7}\\ &\sf{Standard \: Deviation \: = 19.59} \end{cases}\end{gathered}\end{gathered}$

So,

↝ Coefficient of Skewness is given by

$\sf \: Coefficient \: of \: skewness (S_k)= \dfrac{Mean - Mode}{Standard \: Deviation}$

$\sf \: Coefficient \: of \: skewness (S_k)= \dfrac{45.2 - 43.7}{19.59}$

$\sf \: Coefficient \: of \: skewness \: (S_k) = \dfrac{1.5}{19.59}$

$\bf\implies \:Coefficient \: of \: skewness \: (S_k) = 0.077$

Additional Information

The coefficient of skewness is a measure of ASYMMETRY in the distribution.

A positive SKEW indicates a longer tail to the right, while a negative skew indicates a longer tail to the left.

A PERFECTLY symmetric distribution, like the normal distribution, has a skew equal to zero.

For small data sets this measure is unreliable.

Types of Skewness

1. Positive Skewness

If the given distribution is shifted to the left and with its tail on the right side, it is a positively skewed distribution. It is ALSO called the right-skewed distribution.

A positively skewed distribution assumes a skewness value of more than zero. Since the skewness of the given distribution is on the right, the mean value is greater than the median and moves towards the right, and the mode occurs at the highest frequency of the distribution.

2. Negative Skewness

If the given distribution is shifted to the right and with its tail on the left side, it is a negatively skewed distribution. It is also called a left-skewed distribution. The skewness value of any distribution showing a negative skew is always less than zero.

The skewness of the given distribution is on the left; hence, the mean value is less than the median and moves towards the left, and the mode occurs at the highest frequency of the distribution.

4.	A trader sales two horses, each for 1,955. On the sale of one horse he gets a profit of 15%and on the sale of second horse he has a loss of 15%. Find out the total amount of profit orloss. Find the percentage profit or loss on the whole.
Answer» ANSWER: Rs - 90 Step-by-step explanation: Cost Price of first horse sold for Rs 1955 and making a PROFIT of 15% =(1955×100)/115= Rs 1700 Cost Price of second horse sold for Rs 1955, INCURRING a loss of 15% = (1955× 100)/85 = Rs 2300. Total cost Price of the two horses = Rs 1700 + Rs 2300 = Rs 4,000/ Total sale price of the two horses = Rs 1955 × 2 = Rs 3910 Loss on the deal = Cost Price -Sale Price = Rs 4000 - Rs 3910 = Rs 90.

Answer»

ANSWER:

Rs - 90

Step-by-step explanation:

Cost Price of first horse sold for Rs 1955 and making a PROFIT of 15% =(1955×100)/115= Rs 1700

Cost Price of second horse sold for Rs 1955, INCURRING a loss of 15% = (1955× 100)/85 = Rs 2300.

Total cost Price of the two horses = Rs 1700 + Rs 2300 = Rs 4,000/

Total sale price of the two horses = Rs 1955 × 2 = Rs 3910

Loss on the deal = Cost Price -Sale Price = Rs 4000 - Rs 3910 = Rs 90.

Answer» Answer: = 50% I AM SORRY THIS ANSWER IS LATE! BUT I HOPE THIS HELPS OTHER USERS TOOO!! Pls Thank me! And if u by any chance see this plss mark brainliest!! Step-by-step explanation: 1. I would give you the original formular for calculating percentage increase is: *Percentage increase = FINAL population ÷ original price 100 PL= 262500 ÷ 175000 * 100 = 150** Therefore the percentage increase is 150-100 = 50% You might be wondering why u subtract 100 from it. This next procedure which is way more understandable would explain it to you! 2. SIMPLE CROSS MULTIPLIICATION METHODE 100% is normally the highest percentage in math! So first lets make 175000 to be equal to 100% and this is because it is the original population. so, making it equal to hundred per cent indicates there is no recent increase or decrease that this is the "NORMAL" (Assuming that the percentage increase was given you have to add it to 100 to show that there is an increase by this percentage making it no more "Normal", Same applies to percentage decrease you subtract it from 100% to INDICATE that the is a decrease in the "Normal" 175000 = 100% 262500 = x cross multiply 26250000 = 175000x Move the 175000 across the equality SIGN to make x the subject. Normal algebra = 150% (This answer shows as that there was an increase in the population by 50% away for the normal) = 150-100 = 50%

The population of a town increased from 175000 to 262500 in a decade. the average percent increase of population per year is?

Answer»

Answer: = 50%

I AM SORRY THIS ANSWER IS LATE!

BUT I HOPE THIS HELPS OTHER USERS TOOO!!

Pls Thank me!

And if u by any chance see this plss mark brainliest!!

Step-by-step explanation:

1. I would give you the original formular for calculating percentage increase is:

Percentage increase = FINAL population ÷ original price * 100

PL= 262500 ÷ 175000 * 100 = 150

Therefore the percentage increase is 150-100 = 50%

*You might be wondering why u subtract 100 from it. This next procedure which is way more understandable would explain it to you!*

2. SIMPLE CROSS MULTIPLIICATION METHODE

100% is normally the highest percentage in math!
So first lets make 175000 to be equal to 100% and this is because it is the original population. so, making it equal to hundred per cent indicates there is no recent increase or decrease that this is the "NORMAL" (Assuming that the percentage increase was given you have to add it to 100 to show that there is an increase by this percentage making it no more "Normal", Same applies to percentage decrease you subtract it from 100% to INDICATE that the is a decrease in the "Normal"

175000 = 100%

262500 = x

*cross multiply*

26250000 = 175000x

*Move the 175000 across the equality SIGN to make x the subject. Normal algebra*

= 150% (This answer shows as that there was an increase in the population by 50% away for the normal)

= 150-100 = 50%
