What are the uses of bar graphs?
It is a visual display used to compare the amount or frequency of occurrence of different characteristics of data and it is used to compare groups of data.
What is the difference between a histogram and a pareto chart?
Both graphs are used to summarize data. Pareto chart is used to establish differences between different groups of data and will assign relative importance to the different groups of data. Histogram is a data distribution graph that will determine if the particular set of data is symmetric or not.
Why we use bar chart?
Bar Charts are used to compare things between different groups or tracking the changes according to time.
What does a t-test tell you?
A t-test is an assessment of whether the means of two groups are statistically different from one another (running a t-test is appropriate when you want to compare the means of two groups). A t-test tell you the probability that those two sets of values come from different groups.
What is a parametric test used to compare the means of two groups?
t-test

What is the purpose of using different colours to represent different groups of people in double bar graphs?
It makes it easier to identify the different groups visually.
A diagram that graphs the numbers of people of different age groups in the populations is called a what?
A Population Pyramid! :)
Which type of graphs show patterns and make comparison about groups?
All graphs show patterns. Bar charts are one way to show comparisons between groups.
What type of graph would you use to display various types of data?
. . . a Line graph.Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.. . . a Pie Chart.Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.. . . a Bar Graph.Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger.. . . an Area Graph.Area graphs are very similar to line graphs. They can be used to track changes over time for one or more groups. Area graphs are good to use when you are tracking the changes in two or more related groups that make up one whole category (for example public and private groups).. . . an X-Y Plot.X-Y plots are used to determine relationships between the two different things. The x-axis is used to measure one event (or variable) and the y-axis is used to measure the other. If both variables increase at the same time, they have a positive relationship. If one variable decreases while the other increases, they have a negative relationship. Sometimes the variables don't follow any pattern and have no relationship.:)
Do the Physical and chemical properties of halogens compare that of noble gases?
No the properties are different and they belong to two different groups
What is a pi graph?
It's a graph that is a circle that is split up into percentages (%) and for different groups. ;D
Which two types of graphs make comparisons about groups?
Bar and Pictographs
A graph that relates two groups of data?
There can be many, line graphs bar graphs scatter plots, many more, you can look on Google if that doesn't answer anything
What kind of data does a bar gragh show?
A bar graph shows categorical data represented by rectangular bars. Each bar represents a different category and the height of the bar represents the frequency or amount associated with that category. It is commonly used to compare and display data in categories or groups.
