It is used when studying relationships between multiple attributes or features at the same time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s evaluate the choices:<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Vital signs recorded for a newborn baby<\/strong> \u2705<br>This is <strong>multivariate data<\/strong> because multiple variables are being recorded simultaneously \u2014 such as heart rate, temperature, respiration rate, oxygen saturation, etc. These vital signs are all different <em>types of measurements<\/em> collected at the same time for one individual (the newborn), making this a textbook example of multivariate data.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li><strong>Number of songs played in a day by your favourite radio station<\/strong> \u274c<br>This is <strong>univariate data<\/strong>, because it involves just a <strong>single numerical value<\/strong> \u2014 the number of songs \u2014 being recorded per day. There\u2019s only one variable.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li><strong>Daily temperature recorded by a monitoring station in Antarctica<\/strong> \u274c<br>This is <strong>also univariate data<\/strong>. Although it may be recorded over many days (a time series), it&#8217;s still one variable \u2014 temperature \u2014 being measured. The time dimension doesn&#8217;t make it multivariate unless more variables (like wind speed or humidity) are also recorded together.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ol start=\"4\" class=\"wp-block-list\">\n<li><strong>Number of words spoken by President Donald Trump in his inaugural speech<\/strong> \u274c<br>Again, this is <strong>univariate<\/strong>: a single number \u2014 the word count \u2014 for a single event. No additional variables are included.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Summary:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Multivariate data captures <strong>multiple measurements<\/strong> per subject or case. This is essential for complex analysis like regression, clustering, or principal component analysis. Among the options, only the <strong>vital signs of a newborn baby<\/strong> include multiple simultaneous observations, making it the correct example of multivariate data.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following is an example of multivariate data?
