In a statistics class, the standard deviation of the heights of all students was 4.2 inches. the standard deviation of the heights of males was 3.4 inches and the standard deviation of females was 3.3 inches. why is the standard deviation of the entire class more than the standard deviation of the males and females considered separately?

Answer

given,

the standard deviation:-  

of the students height in the class = 4.2 inches  

of the male heights in the class = 3.4 inches  

of females height in the class = 3.3 inches  

standard deviation is the deviation of the value from the target value.

the given question standard deviation of the students is more than that of the individual standard deviation of the heights of males and females because of the distribution of the entire class has more dispersion.

i'm not sure what you mean but in todays world there is a lot of women that are the bread winners in the family. there is a lot more single mothers now that are going back to get an education which is boosting the economy. i believe there has been a boost in the economy due to women the cosmetic industry is boosting, chemist, the sky is becoming the limit for women in todays economy. most women are also putting off having kids just to make sure they have a education. i don't know how these two relate though to scriptures because it's not the way the lord wanted it. the man is suppose to be the bread winner and due to social media and the easy access we have there is a lot of cheating going on.
