Data- a set of numerical or non-numerical information Ways to display data

- Bar Graph - Line Graph - Stem-and-Leaf Plots - Box-and-Whisker Plots - Frequency Tables - Histograms

- Bar Graph -shows the relationship between different values of data -each data value is represented by a column in the graph -the categories of different kinds of data are listed along the horizontal, or x, axis -the quantity or amount of data is listed along the vertical, or y, axis

- Line Graph -shows the relationship between independent and dependent values of data, and are usually used to show trends over time -each data value is represented by a point in the graph that are connected by a line -the independent variable is listed along the horizontal,or x, axis and the quantity or value of the data is listed along the vertical, or y, axis

- Line Graph Kelsey works at an arboretum and tracks tree growth over time. Kelysey collected the growth data of one tree over five years and organized her data into the table below. Create a line graph that represents the data over time. Then state two conclusions about the data.

- Box-and-Whisker Plots -a box plot illustrates the distribution of the data set in quartiles -a box is made around the median, with the sides of the box being the first and third quartiles -the whiskers are the lines extending outwards from either side of the box indicating the range of the data set -can be oriented vertically or horizontally

- Box-and-Whisker Plots Median- the value that is in the middle of the data Range- the difference bet the largest and smalles values - identifies how far apart the values are in the data set Quartiles- divide data sets into four equal groups First quartile- the median of the lower half of the data set Second quartile- the median of the data set Third quartile- the median of the upper half of the data set Minimum- smallest value in the data set Maximum- largest value in the data set

- Frequency Table -shows the frequency, or amount of occurrences, of a specific category or group of data Groups of data are referred to as bins. Bins can be many different sizes, but they never overlap. The size of bins is determined by the range of the data. Range- the difference between the largest and smallest values. - identifies how far apart the values in the data set are

- Frequency Table Twenty people were asked how many hours they sleep each night. The results of the survey are listed below. Create a frequency table to display the data. 7, 8, 6, 9, 10, 12, 5, 7, 8, 9, 10, 11, 12, 7, 6, 7, 8, 10, 11, 9

1. Create a two column table. The left hand column will be the number of hours and the right will be the frequency.

- Histogram

• a vertical bar graph that illustrates the frequency of the data
• A graphical representation of a frequency table
• The horizontal axis lists the bins, or categories of the data
• The vertical axis lists the frequency, or amount, of the occurences.
• Unlike a bar graph, the columns within a histogram do not have space between them

- Histogram The frequency table below shows the number of hours that twenty people said they slept each night. Create a histogram to display the data.
