What is the independent variable in Shawn’s experiment? a. b. c. d. the the time of day number of flowers diameter of the flowers time of year

6. In testing the effectiveness of an energy drink on the performance of athletes, 50 athletes were given water and 50 athletes were given a new energy drink called “Power Up. ” After drinking one can of “Power Up”, each athlete was timed while performing a 30 meter sprint, 50 -sit-ups, and 20 pull -ups. The timed performance of the three athletic events was the. . . ? a. b. c. d. conclusion of this experiment hypothesis for this scenario responding variable (dependent variable) manipulated variable (independent variable)

7. Nick and Doug designed an experiment to find out if goldfish grow larger if fewer fish live in the same bowl. They measured the lengths of seven goldfish and placed them in identical bowls. Two goldfish were placed in one bowl, and the remaining five goldfish were placed in a second bowl (see below). . For three months they poured the same amount of food into each bowl each day, and they maintained the water conditions the same. Then they measured the lengths of all the fish and compared them. What is the responding variable (dependent variable) in this investigation? a. b. c. d. length of the fish number of fish per bowl amount of food per fish condition of the water

I Can… ■ Interpret data from a table ■ Interpret data from a circle graph ■ Interpret data from a line graph ■ Interpret data from a bar graph ■ TOC #7 Interpret data

Copy this down! Data Interpretation in 4 Steps Detailed Version Step 1: Carefully examine the table, graph, or diagram. Step 2: Look for patterns/trends in the way the data is organized and displayed. Step 3: Read the question. Determine specifically what it is asking. Also read the answer choices. Step 4: Again examine the visual to find the answer. Note: often the answer will not be obvious, but it can be determined by analyzing patterns/trends of the displayed data.

What do you notice when you examine this table? Task: Write down three facts about this table. (1) Closely examine the table, graph, or diagram. 12 months City X Avg Temp City Y Avg Temp Avg monthly temp (in Celsius)

What patterns do you see with this data? Task: Write down one pattern that you see. (2) Look for patterns in the way the data is organized and displayed. January February City X-Lowest temps (coldest) are Dec, Jan and Feb December City Y-Lowest temps (coldest) are also Dec, Jan and Feb

What otherinpatterns seeiswith this data? (2) Look for patterns the waydo theyou data organized and displayed. June July August June, July, and Aug are the highest temps (hottest) for both cities

What otherinpatterns seeiswith this data? (2) Look for patterns the waydo theyou data organized and displayed. For both cities the lowest temps happen in the coldest winter months. For both cities the highest temps happen in the summer months. Also for both cities moderate temps occur in spring and fall. January February Spring June July August Fall December Both of these cities have four seasons. This reveals to you something about their locations. (Not all places on Earth have four seasons!)

Is there anything else that you notice about this data? Hint: Lookinatthe theway temps these two cities. and displayed. (2) Look for patterns theof data is organized Which city is warmer? City X is cooler City Y is warmer Since city Y is generally warmer than city X, this reveals to you something about the location of each city. (They are not located in the same area!)

(3) Read the question and determine specifically what it is asking. Ø Also carefully read the answer choices. We know that city X is cooler than city Y. Which one of these answer choices best explains this?

(4) Find the answer (may be in the pattern/trend). …nothing here about wind speed, & this would not make X cooler than Y. So letter A probably is not the right answer. City X is cooler City Y is warmer

(4) Find the answer (may be in the pattern/trend). …nothing here about humidity, & this would not make X cooler than Y. So letter B probably is not the right answer. City X is cooler City Y is warmer

(4) Find the answer (may be in the pattern/trend). …nothing here about rainfall, & this would not make X cooler than Y. So letter D probably is not the right answer. City X is cooler City Y is warmer

(4) Find the answer (may be in the pattern/trend). Cities on the equator are closer to the sun, so these cities are generally hotter than cities in other areas of our planet. So letter C is the correct answer. Ø City X is generally colder than City Y, so it is logical to assume that City X is further from the equator. Ø City X could be Chicago, IL while city Y could be Orlando, FL. City X is cooler City Y is warmer
