Yaya says:
IQ Scores have a bell-shaped distribution with a mean of 100 and a standard deviation of 15. What percentage of IQ scores are between 70 and 130?
<span>Solution: </span>130 – 100 = 30 which is 2(15). Thus, 130 is 2 standard deviations to the right of the mean. 100 – 70 = 30 which is 2(15). Thus, 70 is 2 standard deviations to the left of the mean. Since 70 to 130 is within 2 standard deviations of the mean, we know that <span>about 95% of the IQ scores would be between 70 and 130.</span>
<u>Answer:</u>
Option D. It's important to recognise children when they follow the rules because not doing so can cause them to act out to receive adult attention.
<u>Explanation:</u>
Every human being regardless of his age, expects validation and acceptance from the surrounding in which he lives, children aren’t an exception from the list.
It is most important to recognise the actions of the children when they follow the rules as doing so would encourage them to do the same action when they encounter the same situation in the future and helps in increasing the child’s self image, self esteem and emerging as a self regulating child.
In the case of not recognising the actions would lead to a situation where the children would start breaking the rules, just in order to grab your attention and this would continue in a cyclic manner if it is not treated effectively by the adults which will eventually lead to behavioural problems.
Hence the right answer is, Option D.
