This means that the ability to detect a change in the intensity of a stimulus depends on the magnitude of the original stimulus. The law can be expressed as:<\/p>\n\n\n\n<p>[<br>\\Delta I \/ I = k<br>]<\/p>\n\n\n\n<p>Where:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>( \\Delta I ) is the change in stimulus intensity,<\/li>\n\n\n\n<li>( I ) is the initial intensity of the stimulus,<\/li>\n\n\n\n<li>( k ) is the constant of proportionality (Weber\u2019s fraction).<\/li>\n<\/ul>\n\n\n\n<p>In simpler terms, a small change in intensity is easier to notice when the stimulus is weak, while a larger change is required to notice the difference when the stimulus is strong.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Illustration using the 4 Ps (Product, Price, Place, Promotion):<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Product:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Imagine a <strong>shampoo<\/strong> that is relatively inexpensive (low initial intensity). A slight increase in scent or effectiveness of the product will be noticeable to customers because the change in stimulus is proportionally large compared to the original product quality.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Price:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For a luxury skincare item priced at $200, a small price increase of $10 (5%) might not be as noticeable as the same $10 increase on a $20 item (50%). This follows Weber\u2019s Law because the higher price (greater intensity) requires a proportionally larger change to detect.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Place:<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A new <strong>detergent<\/strong> in a grocery store chain might only show minor differences in availability across different locations.
