Stat. Steps to Determine if Data is Exponential - Cooney

1. graph x and y

2. ratio test
• copy L2 into L3
• copy L2 into L4
• delete first number of L3
• delete last number of L4
• L5 = L3/L4
• common ration = mean of L5 (1-var stat. of L5)

3. graph x, logy
• clear L3, L4, L5
• L3 = log(L2)
• check to see if transformed data is linear… must be on statement of proof: “The transformed data appears to be (roughly/strongly/etc.) linear. Therefore the original data is exponential.”
• graph L1, L3

4. calculate linear regression of x and logy
• (y hat) = a + bx
• (stat  calc  8  L1, L3, Y1)
• put line on graph (step 3)

5. residual plot to determine if truly linear (graph x, resid)
• resid: 2nd  stat  8

6. pattern or not (random scatter = equally spread above and below line)
• write sentence: “If the residual plot shows random scatter, then the transformed data is linear and therefore the original data is exponential.”

7. write equation log(y hat) = a + bx
• simply write equation from step 4 and put “log” in front of (y hat)

8. inverse transformation
• write in exponential form
• (y hat) = 10 (to the) [a + bx] (power)

9. predict


**reference information from problem!**

APES Oceanography Notes - Shope

The formatting here sucks, but I have it nice and pretty (in outline form) with diagrams of the currents if anyone is interested... and if anyone has any questions about this section, let me know. I am obsessed with oceanography. :)

surface currents are caused by wind (and friction)
deep currents are caused by density (caused by temperature and salinity): thermohaline circulation; (a.k.a. density currents)

distribution of water:
o 71% of the Earth is water
o 97% is sea water (salty)
o 3% is freshwater
o 2.997% of which is unavailable for human use (ice, etc.)
o 0.003% available for human use

salts and ocean water
o about 3.5% of ocean water is composed of salt (saline)
o 85% of that is NaCl (regular table salt)
o also: magnesium, sulfur, calcium, potassium

• the bottom of the ocean is basically a nutrient sink… aquatic organisms die and remains fall to bottom

• aquatic biomes: marine (saltwater) or freshwater
• coastal biomes
o estuaries: main breeding grounds
o marsh: coastal wetlands
o tidal pools: intertidal

ENSO (El Niño Southern Oscillation) (“baby boy”)
o not an upwelling
o southern trade winds blow warm equatorial water away from South America and towards Asia as they blow northwest (usual)
o this allows the Peruvian current to upwell with cold, nutrient rich water
o ENSO suppresses upwelling (usual)
o generally happens around Christmastime
o warm water returns toward South America (warm air & clouds return too)
o thermocline is lowered
o less nutrients… less phytoplankton… less fish
o air pressure change: low to South America
o occurs roughly every 3-7 years (hasn’t happened in a while)
o provides fuel for evaporation & storm centers in North America… (ex. ENSO in 1998 caused a lot of snow in Charlotte)
o North American climatologists “discovered” it in 1960s… fishermen in South America had known for 100s of years
o weakens trade winds
o ties into monsoon season in Asia (more monsoons)
o cause of ENSO unknown

La Niña (“baby girl”)
o increase in normal patterns

tides
o the diurnal (daily) cycle of water movement caused by lunar gravity and modified by solar gravity
o tides vary with the moon’s distance in orbit and with coastal features
o occur at intervals of about six ours each day on most ocean coasts
o really only has noticeable effect on oceans
o hardly any effect on climate, but has big ecological effects
o not constant day to day because of orbits and coastal features

types of tides
o high & low
o flood – incoming, low to high
o ebb – outgoing, high to low
o spring – highest tide (MEMS)
o neap – lowest tide

tide frequency
o diurnal – one of each per day
o semidiurnal – two of each per day
o mixed – one & two or two & one

waves
o the passing of a wave is essentially a transfer of energy
o the water within the wave moves in a circular pattern
o the depth of movement (a.k.a. the depth of the wave) is equal to 1/2 the wavelength
o a wave will “break” when the depth of the wave is about 1/20 the wavelength

west wind drift – circles Antarctica (a current)

APES Oceanography Vocab - Shope

littoral: belonging to or found on or near the shore

intertidal
: shoreline area between the high and low tide marks

continental shelf
: that region of the continental land mass submerged under the ocean

continental slope
: the descending drop-off from the continent to the ocean floor

abyssal plain: the bottom of the ocean; the ocean floor; ("abyss" means deep)

seamount: "sea mountain"; often refers to volcanic mountains formed from the abyssal plain

neritic: waters near the shore or coastline

pelagic: the main surface waters of the ocean

benthic: deep ocean waters

gyre: a very large circular flow of water in the ocean; (ring)

thermocline: a layer in a large body of water where the temperature makes a sharp change with a major change in the temperature gradient

halocline: a sharp change in salinity; ("halo" means salt)

plankton: small free floating/drifting aquatic life; vital for life

phytoplankton: photosynthetic (plant) plankton

zooplankton: animal plankton

nekton: swimming (mobile) aquatic life

upwelling: an oceanic process whereby prevailing winds force warm surface water away from coastlines, allowing cool, nutrient rich water to rise to the surface, thus increasing food supplies for aquatic life

wave: the moving swell of water caused by the energy of wind, tides, or currents

wave crest: top (highest point of wave)

wave trough: lowest point between two successive waves

wave height: vertical difference between crest & trough

wave length: horizontal difference between two crests

wave period: elapsed time between two passing crests

wave of oscillation: passage of energy through water without movement of the water; most common type of wave

wave of translation: a near-shore wave that "breaks" causing water to move forward

Psychology Text Notes pg.193-199 - Mason

sensation – the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment

perception
– the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events

bottom-up processing – analysis that begins with the sense receptors and works up to the brain’s integration of sensory information

top-down processing
– information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations

psychophysics – the study of relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experience to them

absolute threshold – the minimum stimulation needed to detect a particular stimulus fifty percent of the time

signal detection theory – a theory predicting how and when we detect the presence of a faint stimulus (“signal”) amid background stimulation (“noise”); assumes that there is no single absolute threshold and that detection depends partly on a person’s experience, expectations, motivation, and level of fatigue

subliminal
– below one’s absolute threshold for conscious awareness

difference threshold – the minimum difference between the two stimuli required for detection fifty percent of the time; we experience the difference threshold as a just noticeable difference; also called just noticeable difference or jnd.

Weber’s law – the principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount)

APES Atmosphere (study guide) - Shope

Considering the fact that everyone on A day has the test tomorrow (or rather, today, considering it's 12:06 AM), I don't think this will be very useful. But anyone who has it on B days?

I have a four-page study guide for the first test on Atmospheres... it has all the notes, the information from the book, and information from the AP book. The formatting doesn't work here, but if anyone reads this before you actually take the test... let me know and I'll happily e-mail it to you.

Good luck on the test!
