Understanding the Relationship Between x and y<\/strong><\/h4>\n\n\n\n<p>The statement &#8220;as x increases, y decreases&#8221; describes a <strong>negative relationship<\/strong> between the two variables. This means that when one variable gets larger, the other tends to get smaller. In other words, the points on a scatter plot would slope <strong>downward from left to right<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>2. Interpreting the Correlation Coefficient (r)<\/strong><\/h4>\n\n\n\n<p>The correlation coefficient <strong>r<\/strong> measures the strength and direction of a <strong>linear<\/strong> relationship between two variables. It ranges from <strong>-1 to +1<\/strong>.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If <strong>r = 1<\/strong>, it&#8217;s a perfect positive linear relationship.<\/li>\n\n\n\n<li>If <strong>r = -1<\/strong>, it&#8217;s a perfect negative linear relationship.<\/li>\n\n\n\n<li>If <strong>r = 0<\/strong>, there is no linear relationship.<\/li>\n\n\n\n<li>If <strong>r is negative<\/strong>, the relationship is <strong>negative<\/strong>, and y decreases as x increases.<\/li>\n<\/ul>\n\n\n\n<p>In this problem, <strong>r = -0.41<\/strong>, which means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The relationship is <strong>negative<\/strong> (since the sign is negative).<\/li>\n\n\n\n<li>The relationship is <strong>moderate to weak<\/strong>, because the value is not close to -1.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>3. Matching the Graph<\/strong><\/h4>\n\n\n\n<p>You should look for a graph that shows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A <strong>downward trend<\/strong> from left to right, since the relationship is negative.<\/li>\n\n\n\n<li><strong>Scattered points<\/strong> with a <strong>moderate<\/strong> trend\u2014not a strong line, but not completely random either.<\/li>\n<\/ul>\n\n\n\n<p>Among the options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Graph A or C<\/strong> may show positive trends.<\/li>\n\n\n\n<li><strong>Graph B<\/strong> could show no relationship (r near 0).<\/li>\n\n\n\n<li><strong>Graph D<\/strong> likely shows a <strong>moderate negative trend<\/strong>, which matches an <strong>r of -0.41<\/strong>.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">\u2705 Therefore, the best representation is <strong>Graph D<\/strong>.<\/h3>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner9-325.jpeg\" alt=\"\" class=\"wp-image-232597\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Which graph best represents the following situation?
