Random Sample a sample in which each member of the population hasequal chance of being selected.
Population the complete collection of the group to be studied.
Sample part of the population.
Mean the sum of the values divided by the number ofvalues in the data set.
Median the middle value.
Mode the value that occurs most often.Sometimes there is no mode.
Range Find the difference between the least and greatest values.
Frequency Table organizes data into groups.
Cumulative Frequency Table includes a running total of the frequencies of all the previous groups.
Stem and Leaf Plot shows how often data values occur and how they are distributed. Numbers are separated into two parts: the stem and the leaves. The stem shows the leftmost digit in each number,and the leaves show the rightmost digit in each number.
Bar Graph and Double Bar Graph uses bars to compare data.A graph compares two sets of data.
Histogram is used to represent data in a frequency table. The bars touch and both axes show numerical data.
Box and Whisker Plot presents a summary of a set of data bypresenting the data in four equal parts.
Ways graphs can be misleading • An axis is “broken” or numbers are left out on an axis.• The intervals on an axis are not the same length.• Different sizes are used to represent bars in a bar graph.• Pictorial graphs could distort the data.
