Our lifespan is insignificant. During the dinosaur years, their were 370 days in a year. Now there’s only 365 days. Did you know that 1 billionth of the suns actual energy, hits the earth. To get out all the water in the world, it would take 46 years. That includes all the oceans, seas, and lakes. The carbon cycle also pulls carbon dioxide into to the sea. It’s passed on as a food chain. The massive explosion of of heat is called a supernova. A supernova is when the sun explodes. But that wont happen for billions of years. The clouds in space look like dust particles and out clouds are actually water vapors. The energy released from space, pushes outwards. When gravity looses grip on our earth, it is called the dark energy. Our universe is in no danger and we are also called “The Milky way”. Protons will slowly degrade. Another “Einstein” that is a scientist, is called Steven Hawkins.

Central Tendency
Range and measures of central tendency
-range and measures of central tendency (mean, median, and mode) are values that summarize a set of data. They are useful when analyzing data.
Range -The difference between the greatest and the least values in a data set
Mean (Average) -The sum of a set of data divided by the number of data.
- -Find the sum
- -And divide by the # of data.
Median -The middle value of a data set.
- -Chronological order
- -If you end up with 2 numbers, find the mean of the 2 numbers
Mode -The most common value of a data set.
- -Place them in order.
- -Some don’t have modes.
Outliers -Sometimes there are extreme values that are separated from the rest of the data. These extreme values are called outliers. Outliers affect the mean.
Central Tendency- referring to range, mode, median, mean.
