INPUT ARTICLE: Article: If you're ready to plant the tree, purchase Arborvitae saplings from a nearby garden center or nursery. Look for Arborvitae saplings with a healthy, green color and no signs of sickness or damage. If it's not currently spring or fall and you have time to sprout the tree, plant Arborvitae seeds in a pot and raise them to saplings indoors. Once you reach planting season, you can transfer your Arborvitae tree outdoors. Arborvitae trees can only grow indoors as saplings. To reach their maximum height and stay healthy, they must grow to maturity outside. Arborvitae trees make great natural fences or hedges. If planting multiple arborvitae trees, dig holes in an evenly spaced line for even landscaping lines. Space your Arborvitae saplings at least 2 feet (0.61m) apart to give them room to grow. Place wooden stakes wherever you want to plant a tree for an organized layout. Turn the pot upside down and gently tap on its bottom to loosen the tree and lift it out by the trunk. Pull at the tree's root ball, loosening any external roots to help them absorb more nutrients when you plant it. Loosen the root ball carefully to prevent damaging your tree. Measure the root ball from top to bottom, then side to side, and write its measurements down. First, dig down far enough to fully cover the root ball, then make the hole 2-3 times as wide as your root ball so that the soil will be loose enough for the roots to grow. If your root ball has a 12in (30cm) diameter, for example, dig a 12in (30cm) deep hole. Mix compost into your soil before filling in the hole so that the root bulb will receive more nutrients. You'll want to cover the roots with soil but not any of the tree's trunk to prevent root rot. Lower the tree carefully into the hole and, when finished, cover its roots up with soil. Inspect the tree afterward to make sure you don't expose the roots or accidentally bury the trunk. Before you bury the tree, make sure that it's level with the ground. Otherwise, the tree may permanently lean. Burying the trunk can cause your tree to develop fungal infections and other diseases.

SUMMARY: Buy Arborvitae saplings if you want to plant them immediately. Grow Arborvitae seeds in pots if you can wait to plant them. Align your arborvitae trees in rows. Remove your tree from the pot and tease its roots. Dig a hole at approximately the same depth as the root ball. Position the tree into the hole and cover it with dirt.

INPUT ARTICLE: Article: You will need one egg (raw or hard boiled but hard boiled is best) and one spoon for each person participating in the race. You might even like to use dyed Easter eggs as something special for Easter. It's best to have this race on grass or some other soft surface, to give dropped eggs a chance! It's no fun dropping your egg, thinking you've won, only to realize that the finish line is in fact several inches or centimeters away. Everyone then begins to race towards the finish line. The contestants have to keep their egg balanced in their spoon, without using their other hand for support. If the egg drops, but is not broken, the contestant can pick up the egg and resume the race. The first contestant to make it to the finish line wins. Have second and third prizes, too.

SUMMARY: Assemble the items you'll need. Line the contestants up next to each other on a starting line. Have your finish line visible and clear. Give your signal for the race to start. Declare the winner.

INPUT ARTICLE: Article: In the fourth column of your data table, you will calculate and record the error of each predicted value. Specifically, subtract the predicted value (y{\displaystyle y^{\prime }}) from the actual observed value (y{\displaystyle y}). For the data in the sample set, these calculations are as follows: y(x)y(x){\displaystyle y(x)-y^{\prime }(x)} y(1)y(1)=22.8=0.8{\displaystyle y(1)-y^{\prime }(1)=2-2.8=-0.8} y(2)y(2)=43.4=0.6{\displaystyle y(2)-y^{\prime }(2)=4-3.4=0.6} y(3)y(3)=54=1{\displaystyle y(3)-y^{\prime }(3)=5-4=1} y(4)y(4)=44.6=0.6{\displaystyle y(4)-y^{\prime }(4)=4-4.6=-0.6} y(5)y(5)=55.2=0.2{\displaystyle y(5)-y^{\prime }(5)=5-5.2=-0.2} Take each value in the fourth column and square it by multiplying it by itself. Fill in these results in the final column of your data table. For the sample data set, these calculations are as follows: 0.82=0.64{\displaystyle -0.8^{2}=0.64} 0.62=0.36{\displaystyle 0.6^{2}=0.36} 12=1.0{\displaystyle 1^{2}=1.0} 0.6=0.36{\displaystyle -0.6=0.36} 0.2=0.04{\displaystyle -0.2=0.04} The statistical value known as the sum of squared errors (SSE) is a useful step in finding standard deviation, variance and other measurements. To find the SSE from your data table, add the values in the fifth column of your data table. For this sample data set, this calculation is as follows: 0.64+0.36+1.0+0.36+0.04=2.4{\displaystyle 0.64+0.36+1.0+0.36+0.04=2.4} The Standard Error of the Estimate is the square root of the average of the SSE. It is generally represented with the Greek letter {\displaystyle \sigma }. Therefore, the first calculation is to divide the SSE score by the number of measured data points. Then, find the square root of that result. If the measured data represents an entire population, then you will find the average by dividing by N, the number of data points. However, if you are working with a smaller sample set of the population, then substitute N-2 in the denominator. For the sample data set in this article, we can assume that it is a sample set and not a population, just because there are only 5 data values. Therefore, calculate the Standard Error of the Estimate as follows: =2.452{\displaystyle \sigma ={\sqrt {
rac {2.4}{5-2}}}} =2.43{\displaystyle \sigma ={\sqrt {
rac {2.4}{3}}}} =0.8{\displaystyle \sigma ={\sqrt {0.8}}} =0.894{\displaystyle \sigma =0.894} The Standard Error of the Estimate is a statistical figure that tells you how well your measured data relates to a theoretical straight line, the line of regression. A score of 0 would mean a perfect match, that every measured data point fell directly on the line. Widely scattered data will have a much higher score. With this small sample set, the standard error score of 0.894 is quite low and represents well organized data results.

SUMMARY:
Calculate the error of each predicted value. Calculate the squares of the errors. Find the sum of the squared errors (SSE). Finalize your calculations. Interpret your result.
