New Vocabulary: Math Terms. Bias- A systemic error in sample statistics that can occur from the use of. Data- Information (such as age, color, or shape) gathered concerning a sample or. Mean- The average value found by adding the values for all the members of the sample. The mean can be skewed to one. Measures of Central Tendency- Numerical values that are located, in some sense, in the middle of a sample. These include the mean, median, and mode. Median- The value that falls in the middle of a sample; there are as many members. Since the median falls in the middle of the. Min/max plot- A visual representation of the range. It shows the dispersion of the data. Rent Galaxy Hunter (2004) and other Movies & TV Shows on Blu-ray & DVD. 1-month free trial! Fast, free delivery. No late fees.

Population- All members of some set that, as a whole, is generally too large to study. Sometimes the term population refers to people or objects; other times it. Both meanings are used. Population Parameter- The theoretical descriptive measure on the scores of the population. Generally. a population is too large to record all the scores but theoretically, the. The goal of sample statistics is to be able to infer something meaningful. Random Number Table- A list of random numbers from which single digit (0- 9), double digit (0. These numbers can then be used to identify the members. Most. random number tables include a suggestion for how to use them. Range- The simplest measure of dispersion. ![]() Galaxy Hunter Teacher Page: Lesson Plan.

Sample- A subset of the population obtained by collecting information only about some. Sometimes the term sample refers to people or objects. Both meanings. are used and the context usually tells which one is meant. Sample statistic- Any descriptive measure on the scores of a sample, such as the mean, median. Simple random sample (SRS)- A simple random sample is gathered by selecting each member without replacement. The members are selected by chance so that each member has an equal opportunity. The sample, of size n, is representative of the population. Smallest Reasonable Sample- Statisticians look for the smallest sample that is reasonable. The smallest. sample minimizes time and costs. A reasonable sample is one that is unbiased. Science Terms. Bulge- The bulge is a spherical structure at the center of spiral galaxies. ![]() The bulge of. the Milky Way is about 3. Disk- The disk is a pancake- shaped structure in spiral galaxies and is composed. Some. old stars are also present. The disk contains the spiral arms and slices through. The disk in the Milky Way is about. Elliptical Galaxy- A galaxy having an oval or nearly spherical shape. Some are more elongated. Resembling a bulge and halo, it is composed mostly of old stars. The smallest elliptical galaxies (called. Galaxy- A galaxy is an enormous collection of a few million to trillions of. They can be several thousand. Halo- The halo extends outward from the bulge and disk, and contains clusters. In the Milky Way, the halo measures about 1. Hubble Deep Fields (HDFs)- These are the deepest, sharpest, multi- color, optical wavelength images of. The images were made by aiming the telescope at one. There are two HDFs - one in the northern sky. Hubble Space Telescope- An automated reflecting telescope which orbits the Earth, built by the National. Aeronautics and Space Administration and the European Space Agency. It contains. instruments capable of receiving many types of radiation. Irregular Galaxy- A galaxy whose shape is neither elliptical nor spiral. It contains both young. These galaxies often have. Sometimes the irregular shape of these galaxies. Observations such. Hubble Deep Fields show that irregular galaxies were more common in. Light- year- The distance traveled by light in a full year - some 1. To calculate the distance light travels in one year. LY = (3. 00,0. 00 km/s)(3. Milky Way- The specific galaxy to which our solar system belongs, so named because. The Milky Way is a spiral galaxy. Redshift- When an object is moving away from an observer, the light it emits appears. This effect is similar. Doppler effect). For example, the pitch of a fire truck's siren. The pitch drops significantly as the truck passes. When dealing with light, the shift to longer wavelengths is. The wavelength shift occurring when objects are moving. The cosmological redshift tells. Spiral Arms- Pinwheel shaped features located in the disk of a spiral galaxy. The. new bright blue stars that are born there make the spiral pattern visible. Spiral Galaxy- A galaxy made up of a disk with spiral (pinwheel- shaped) arms, a bulge near. The sizes of the disk and bulge vary. The galaxy is. composed of a mixture of old and young stars as well as gas and dust. The. spiral arms are sites of active star formation. The majority of large galaxies. Whole population of HDFs- Astronomers counted and classified all the galaxies that they could reliably. Deep Fields. General Misconceptions: Math Misconceptions. Students may seem to think that any way they choose data will give results. Humans are not good at selecting data in a. Students might think that closing eyes and picking a sample by pointing a. Bias is introduced when the student decides. Also, the student will have a mental image. Science Misconceptions. Students may think that galaxies are static and do not change with time. In fact, galaxies are dynamic and change over millions of years. Preparation Time: Time necessary to download computer software to support the lesson. Teachers should allow time to preview the lesson and to read the science. These pages will provide additional content that will. By previewing the lesson plan, teachers will be able to select an engagement. Execution Time by Module: The amount of time needed to complete any of these modules will vary depending. One possible way to jumpstart your lesson and eliminate the. Use an. overhead, an LCD, or a TV monitor to project the lesson to the class. The. following are estimated times: Start Safari 1. Bias 1. 0- 1. 5 minutes. Sample Size 1. 5- 2. HDF- N vs. HDF- S 1. Last Stop 5- 1. 0 minutes. Physical Layout of Room: Students can work in groups of two or individually in a computer lab. Adaptations. can be made to accommodate classrooms with only a single computer having Internet. This might include using an overhead projector with an LCD that projects. You can also do Galaxy Hunter off- line. Different software programs provide. Internet. Their programs allow you to save web pages. Using your Netscape browser you can open the web. Internet. Using. this option, however, will deny students access to the references (identified. Grab Bag pages) available on the World Wide Web. Materials: This lesson requires a computer with a color monitor and Internet connection. The Web browser used must have at least the capability of Netscape's Navigator. Internet Explorer 4.

Grab Bag section of this lesson, under Downloadable Documents, to monitor. Procedure / Directions: This is a self- directed interactive computer activity. Students may work. Engagement Activity: Step- by- step Instructions: These are self- directed activities. Students can work independently or. The "One- Computer Classroom". Start Safari After choosing one of the Deep Fields and hand- picking a sample. This leads students. Bias Bias is explored when the students decide which of several sampling. They see how bias affects the percentage of irregular. Deep Field. Sample Size The optimal sample size is determined by exploring sample variability. The concept of variability is introduced through a min/max plot of 5 samples. The concept is then. The mean and median are added to the smaller sample sizes in order to pinpoint. The point where this first occurs is the smallest. Students' understanding is checked by asking them. HDF. HDF- N vs. HDF- SIn this assessment, students generate a sample from the other Deep Field. This provides. students with a real- life example of how statistics can be used by scientists. The Last Stop One of the fundamental questions in astronomy asks how galaxies. The Hubble Deep Fields provide a glimpse into the history. Students will be asked whether or not they think the distant universe. The activity concludes by revealing that. This is one of the most intriguing results from. Hubble Deep Fields. Evaluation / Assessment: There are several assessment activities/questions within this lesson. Students. are asked to decide between biased and unbiased sampling methods and queried. The Galaxy Hunter Travelogue provides additional questions to assess students'. Solutions to the Student Travelogue. What method, if any, did you use to select your sample of galaxies? Students may have selected the galaxies by size, shape, color, or location.
