This video explains how to find the median and mode for a set of data. It also explains how to interpret this data to find trends.

• 00:00:00 In this second video, we learn how to find the median and fashion trends. We look at how to interpret data regarding age groups of 15 children who belong to a salsa group. Then, we find the local and central trends using the three measures of location or trend center, and then interpret them. The median is found by summing up the values of each data point, and is equal to 10. We then look at the median using ascending order, starting with the smallest data point. The median for this group of data is 8. The next data point is 10, which is equal to 1 + 2 + 3 + 4 + 5 + 6 + 7. The median for this group is 8, which is equal to 10 divided by 7.5. Next, we look at the trend center using the same method. The trend center for this group is 8. The next data point is 11, which is equal to 1 + 2 + 3 + 4 + 5 + 6. The trend center is 8, which is equal to 10 divided by 11. The trend center for this group is 8, which is equal to 10 ÷ 11, or 0.8. The third measure of trend is location. We look at how often
• 00:05:00 The video explains that, according to data, a third conclusion can be made: that 40% of children are younger than 10 years old. Then, it states that, based on the median, the middle is the data point for half of the population (50% of the population is equal to or greater than their age, or the 50% who are equal or greater than their age). The third conclusion is that, in general, half of the population is younger than 10 years old. This can be useful information for making decisions based on this information. Finally, the last conclusion is that, based on the data, one-fourth of the population is younger than 10 years old. This can be used to estimate that a little less than one-half of the population (47.5%) is younger than 10 years old.
