To find the median, upper quartile, and lower quartile of 12 numbers, you would first need to arrange the numbers in ascending order. The median would be the middle number, or the average of the two middle numbers if there is an even number of values. The lower quartile would be the median of the lower half of the data set, and the upper quartile would be the median of the upper half of the data set. **

To determine the median in a boxplot, you would locate the line inside the box, which represents the median value of the data. The upper quartile is the median of the upper half of the data, and the lower quartile is the median of the lower half of the data. In a boxplot, the upper and lower quartiles are represented by the top and bottom lines of the box, respectively. These quartiles divide the data into four equal parts, with the median at the center. **

The second quartile, also known as the median, is the middle value in a dataset when it is ordered from smallest to largest. It divides the data into two halves, with 50% of the values falling below it and 50% falling above it. The second quartile is a measure of central tendency that is less affected by extreme values compared to the mean. **

The fourth quartile is the highest 25% of a data set when it is divided into four equal parts. It represents the upper range of the data and contains the highest values. In terms of a distribution, the fourth quartile includes the top 25% of the data points, with the remaining 75% falling into the first three quartiles. The fourth quartile is often used to identify outliers or extreme values in a data set. **

No, it is not correct. To draw a box plot, you need five pieces of data: the minimum value, the lower quartile, the median, the upper quartile, and the maximum value. These five values are used to create the box and whisker plot, which provides a visual representation of the distribution of the data, including the range, median, and quartiles. **

In the context of jobs, the term 3rd quartile refers to the point at which 75% of the salaries fall below a certain level. This means that if a job's salary is in the 3rd quartile, it is higher than 75% of the other salaries in the same category. It can be used to understand where a particular job's salary falls within the distribution of salaries for similar positions, and can help job seekers and employers gauge the competitiveness of the salary being offered. **

Longines is a luxury watch brand that is known for its high-quality craftsmanship and attention to detail.

The Kitchen Aid Artisan mixer may squeak due to a few reasons. One common cause is that the gears inside the mixer may need to be lubricated. Another reason could be that the attachments are not properly secured, causing friction and noise. Additionally, if the mixer is being used at a high speed for an extended period of time, it may also start to squeak. Regular maintenance and proper usage can help prevent the squeaking noise. **
