Created with Fabric.js 1.4.5 Mean Median Mode and Range A bar chart or bar graph is a chart with rectangular bars with lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column bar chart.A bar graph is a chart that uses either horizontal or vertical bars to show comparisons among categories. One axis of the chart shows the specific categories being compared, and the other axis represents a discrete value. Example of a bar chart The MeanTo find the mean, youneed to add up all thedata, and then dividethis total by the numberof values in the data. Data Handling Data can be displayed in various ways including bar chart, line graph, pie chart, pictograms and tally chart and many others. There are also Mean, Mode, Median and Range. Data is the food of statistics. Data means any item of information however presented or represented. The ModeThe mode is the valuewhich appears the mostoften in the data. It ispossible to have morethan one mode if thereis more than one valuewhich appears the most.only). The MedianTo find the median, youneed to put the valuesin order, then find themiddle value. If there aretwo values in the middlethen you find the meanof these two values. The RangeTo find the range, youfirst need to find thelowest and highest valuesin the data. The range isfound by subtracting thelowest value from thehighest value. A line chart or line graph is a type of chart which displays information as a series of data points called 'markers' connected by straight line segments. It is a basic type of chart common in many fields. It is similar to a scatter plot except that the measurement points are ordered (typically by their x-axis value) and joined with straight line segments.
