Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): When correlation coefficient (r) is between +0.75 and +1, high degree of positive correlation and when it is between –0.75 to –1 high degree of negative correlation.
Reason (R): The value of correlation lies between + 1 and – 1.
  • a)
    Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of the Assertion (A).
  • b)
    Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
  • c)
    Assertion (A) is true, but Reason (R) is false.

Assertion (A): When correlation coefficient (r) is between 0.75 and 1, there is a high degree of positive correlation. When it is between –0.75 and –1, there is a high degree of negative correlation.

Reason (R): The value of correlation lies between 1 and –1.

The correct answer is option B, which states that both the Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion. Let's analyze this in detail:

Understanding Correlation Coefficient:
The correlation coefficient (r) measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation.

Positive Correlation:
When the correlation coefficient (r) is between 0.75 and 1, it indicates a high degree of positive correlation. This means that as one variable increases, the other variable also tends to increase. The closer the correlation coefficient is to 1, the stronger the positive correlation.

Negative Correlation:
When the correlation coefficient (r) is between -0.75 and -1, it indicates a high degree of negative correlation. This means that as one variable increases, the other variable tends to decrease. The closer the correlation coefficient is to -1, the stronger the negative correlation.

Range of Correlation Coefficient:
The correlation coefficient (r) ranges from -1 to 1. A correlation coefficient of 1 indicates a perfect positive correlation, where all data points lie on a straight line with a positive slope. A correlation coefficient of -1 indicates a perfect negative correlation, where all data points lie on a straight line with a negative slope.

Explanation:
The Assertion (A) is true because when the correlation coefficient (r) is between 0.75 and 1, it indicates a high degree of positive correlation. Similarly, when the correlation coefficient (r) is between -0.75 and -1, it indicates a high degree of negative correlation.

However, the Reason (R) is not the correct explanation of the Assertion. The Reason simply states that the value of correlation lies between 1 and -1, which is true but does not explain why a correlation coefficient between 0.75 and 1 represents a high degree of positive correlation, or why a correlation coefficient between -0.75 and -1 represents a high degree of negative correlation.

Hence, option B is the correct answer as both the Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.

Read the following passage and answer the question that follows:Happiness is considered as a kind of positive emotion which has a significant impact on the physical, cognitive and psychological mechanisms and improves human performance in different fields. This research aims to study the correlation between happiness and death anxiety in health personnel of Zareh hospital in the city of Sari. The current research is a descriptive cross-sectional and correlative study. The population includes all of the health personnel of Zareh hospital located in the city of Sari and they are 226 individuals. Two questionnaires of Oxford Happiness Questionnaire and Templer’s Death Anxiety Questionnaire were completed and surveyed by 144 individuals (97 females and 47 males) of health personnel chosen by simple random sampling. In order to analyze data, the inferential and descriptive statistics including simultaneous equation regression model, Pearson's correlation coefficient, cut-point, and t-test were used for two independent groups. Research results showed that for each one unit of increase in the variable of happiness 0.27 is decreased from the personnel’s’ death anxiety. Thus there is a significant and inverse correlation between two variables of personnel’s happiness and death anxiety. Also another part of the results showed that the difference between females’ happiness and males’ happiness was not significant.Q. ..................... (//) between happiness and death anxiety is being studied.
