If the number of observations is even, then the median is defined as the average of the two middle observations<span>. Median is a measure of central tendency, it depicts the middle value in a given set of numbers. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean or average of the middlemost numbers. If there is an odd number of results or items, the median is the middle number.</span>
Answer:
Changes in solar intensity do not seem to contribute to the change in global temperatures. If they did, the temperatures would rise and fall with the Sun's energy. Instead, the global temperatures continue to rise despite the Sun's natural fluctuations.
Explanation:
Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Since the beginning of the Industrial Revolution, people have burned more and more fossil fuels and changed vast areas of land from forests to farmland.
Ans: Most genes contain the information needed to make functional molecules called proteins. (A few genes produce regulatory molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell.
