Bar Graphs 5SDAP. A bar graph displas data using vertical or horizontal bars that do not touch. Bar graphs are often a good wa to displa and compare data that can be organized into categories. EXAMPLE Use the bar graph to answer each question. A Which language has the most native speakers? The bar for Mandarin is the longest, so Mandarin has the most native speakers. B About how man more people speak Mandarin than speak Hindi? About 500 million more people speak Mandarin than speak Hindi. You can use a double-bar graph to compare two related sets of data. Most Widel Spoken Languages English Hindi Mandarin Spanish 0 00 00 600 800,000 Number of speakers (millions) EXAMPLE The table shows the life epectancies of people in three Central American countries.

Sampling 6SDAP. A population is a group that someone is gathering information about. A sample is part of a population. For eample, if 5 students are chosen to represent a class of 0 students, the 5 chosen students are a sample of the population of 0 students. The sample is a random sample being chosen. EXAMPLE if ever member of the population had an equal chance of Jamal telephoned people on a list of 00 names in the order in which the appeared. He surveed the first 0 people who answered their phone. Eplain whether the sample is random. Names at the beginning of the list have a greater chance of being selected than those at the end of the list, so the sample is not random. PRACTICE Eplain whether each sample is random.. Rebecca surveed ever person in a theater who was sitting in a seat along the aisle.. Inez assigned 50 people a number from to 50. Then she used a calculator to generate 0 random numbers from to 50 and surveed those with matching numbers. Bias 6SDAP. Bias is error that favors part of a population and/or does not accuratel represent the population. Bias can occur from using sampling methods that are not random or from asking confusing or leading questions. EXAMPLE Jenn went to a movie theater and asked people who eited if the agree that the theater should be torn down to build office space. Eplain wh the surve is biased. People usuall onl go to movies if the enjo them, so those eiting a movie theater would not want it torn down. People who do not use the theater did not have a chance to answer.
