Kiwi Bird Problem
As is commonly known, KIWI-birds are native to New Zealand. They are born exactly one foot tall and grow in one foot intervals. That is, one moment they are one foot tall and the next they are two feet tall. They are also very rare. An investigator goes to New Zealand and finds four birds. The mean of the four birds is 4, the median is 3, and the mode is 2. What are the heights of the four birds?
Hint - examine the constraints of the mode first, the median second, and the mean last.
Submit your initial thoughts regarding your research journal paper in relation to the topics we have discussed so far.
Organization of Data
Data can be further classified as ungrouped or grouped. Ungrouped set of data means raw or not arranged in any order, while grouped is data organized and presented in table form. Whether grouped or ungrouped, data can be organized with the help of measure of central tendency, measure of dispersion, and quantiles.
For this lesson, we will be discussing measure of central tendency and measure
