2. Terms to Know Random Samples- A group that represents the entire population fairly Frequency Distribution-Ordering data into intervals and their corresponding freq. Relative Frequency-Frequency of that interval divided by the total frequency Interval width-Subtract the smallest value from the largest & divide by the # of intervals Histogram- A bar graph where the bars are touching(horizontal=intervals vert. = freq. Normal Distribution-Bell shaped curve where most data points are centered Cumulative Frequency Polygon- Line graph that answers the question “How many are less than or equal to a certain number?” Cumulative Frequency-The freq. of that interval plus the freq. of all lesser intervals Central angle of a pie chart- Relative frequency of that category x 360 Truncated graphs-Misleading because of the inconsistent scale Stem-and-Leaf Plot-Line up the stems, find a stem for each leaf, be organized Index Number-(Given year/base year) x 100
