Pearson's correlation coefficient, also known as the product moment correlation coefficient (PMCC), and denoted by r, is a measure of linear agreement between two random variable. It can take any value from -1 to +1. +1 indicates a perfect positive linear relationship between the two variables, a value of 0 implies no linear relationship whereas a value of -1 shows a perfect negative linear relationship. A low (or 0) correlation does not imply that the variables are unrelated: it simply means a there is no linear relationship: a symmetric relationship will give a very low or zero value for r.The browser which we are compelled to use is not suited for any serious mathematical answer and I suggest that you look up Wikipedia for the formula to calculate r.
Taken from the Primary Test of Nonverbal Intelligence (PTONI) Manual: The Primary Test of Nonverbal Intelligence (PTONI) is a standardized norm-referenced test of reasoning abilities (e.g. sequencing, visualization, conceptualization) in young children. The nonverbal format of the PTONI requires no oral responses and minimal motor responses, thus reducing the potential for language differences or delays or motor impairments to confound results. Psychologists, diagnosticians, special educators, speech-language pathologists, and other professionals can use this test to identify both severe intellectual deficits and superior cognitive intelligence. The test was normed on a diverse sample of 1,010 children residing in 38 states. The PTONI is a quick, accurate and cost-efficient way to measure intelligence. Testing takes approximately 5 to 15 minutes.
A quantitative assessment involves numbers. This says 45% so it is quantitative. Qualitative would involve a description: fairly efficient, very efficient or more efficient than before.

All the answers are correct.A biological component of intelligence has to do with how efficient a brain is in processing information.The more complex the task involving reaction time, the stronger the correlation is with intelligence.There is a correlation between reaction time and intelligence. A+ all the answers are correct.

Given co-efficient of determination, r2 = 0.81. co-efficient of correlation, r = square root of 0.81 = +0.9, if the data have move in the same direction.(Let x and y as variables then x and y have linear relationship and x increase or decrease and y also have increase or decrease) = -0.9, if the data have move in the opposite direction.(Let x and y as variables then x and y have linear relationship and x decrease or increase and y is also increase or decrease)
Older people often have more life experiences and accumulated knowledge that can contribute to higher intelligence. Additionally, the aging brain may have developed more efficient processing patterns. However, intelligence is a complex trait influenced by a variety of factors, and younger people can still excel in areas such as creativity and adaptability.

The correlation coefficient is unaffected by change of origin or scale unless one of the sets of variables is multiplied by a negative term, in which case the correlation coefficient will become negative.
Both hard work and intelligence are valuable attributes in achieving success. Hard work can compensate for lack of intelligence, while intelligence can make hard work more efficient. Ultimately, a combination of both traits is often the most effective approach.
both make more efficient products
Memory processes become less efficient, wisdom is unaffected, and creativity may increase
Somatic education describes the way people use self-awareness when they move their bodies. The term is used by Moshe Feldenkrais in his Feldenkrais method, and in Joseph Heller's Hellerwork, another system of body work. Feldenkrais theorized that if we use thought and movement together, as our body movement becomes more efficient, our creativity and intelligence would be enhanced.
Cephalization refers to the concentration of sensory and neural structures in the head region of an organism. Generally, animals with a higher degree of cephalization tend to exhibit more complex behaviors and cognitive abilities. This is because a concentrated nervous system in the head allows for more efficient processing of information and is often associated with higher levels of intelligence.
