What else can I help you with?
What information is lost when a histogram is used to represent a data distribution of a dot plot?
The main loss is the correlation, if any, between the variables. You also lose the exact value of individual data points.
How do you work out the area of a histogram?
A histogram consists of rectangular bars. The area of each is its base times its height. Multiply these together, ensuring that you include any scale factors in your calculations.
What intervals would you use to make a histogram?
Any intervals which are convenient to construct and also make some logical sense.
Does bar graphs touch?
Everyone including books and people answering on this website get this wrong. It does matter and the rule is simple. If your horizontal access is something where it is not possible to rank in any special order- for example favourite crisp flavours or different ways of getting to work - then the bars are separate. I think spacing of a third or half the bar width looks neatest. If you have a horizontal axis of some grouped data, like length of leaves, then you have a histogram and the bars touch. Strictly a histogram has a vertical axis of density to accommodate different width groupings. In many cases all the widths are identical and you have a simple frequency up the vertical axis. There does not seem any unaminity of the correct name for this animal. On the one hand I'd use "histogram" so it's clear the bars touch but then some purists object because the vertical axis isn't density. On balance I'd still call it a histogram.
What is the difference between a bar graph and a histogram?
What is the difference between a bar graph and a histogram?There are two differences, one is in the type of data that is presented and the other in the way they are drawn.In bar graphs are usually used to display "categorical data", that is data that fits into categories. For example suppose that I offered to buy donuts for six people and three said they wanted chocolate covered, 2 said plain and one said with icing sugar. I would present this in a bar garph as:Histograms on the other hand are usually used to present "continuous data", that is data that represents measured quantity where, at least in theory, the numbers can take on any value in a certain range. A good example is weight. If you measure the weights of a group of adults you might get and numbers between say 90 pounds and 240 pounds. We usually report our weights as pounds or to the nearest half pound but we might do so to the nearest tenth of a pound or however acurate the scale is. The data would then be collected into categories to present a histogram. For example:might be a histogram for heights (with the appropriate scale on the vertical axis). Here the data has been collected into categories of width 30 pounds.The difference in the way that bar graphs and histograms are drawn is that the bars in bar graphs are usually separated where in histograms the bars are adjacent to each other. This is not always true however. Sometimes you see bar graphs with no spaces between the bars but histograms are never drawn with spaces between the bars.
Is any set of data can be displayed using is true or false?
true
What is the area under the curve for the histogram below?
There is no histogram below.However, the area under the curve for any histogram is the total frequency.
What is limitation of any map?
The accuracy or sensitivity of the data that is displayed on the map, it is only as good as the data it is built on.
What type of scores represents a histogram?
A histogram represents the distribution of scores in a dataset by organizing them into equally spaced intervals or bins along the horizontal axis, and displaying the frequency or count of scores within each bin on the vertical axis. The scores on the horizontal axis could be any type of numerical data, such as test scores, heights, or ages.

How does XML describe data?
xml uses tags to describe data, any computer can then read the data using the tags.
How should the data be displayed to make the most convincing argument that more yellow paint was used than any other color?
circle graph
What would you use to determine how close to the true value an experimental value is?
I would begin by making some plots of the data: histogram, empirical distribution function in particular. My main concerns would be: presence of outliers, clear mode, enough data to define a clear histogram. I would watch for any apparent anomalies. If it appeared that the data approximated a normal distribution then I would probably measure scale with standard deviation. In other cases, I might first try to transform the data. In fact, this could be an initial option prior to plotting if the data is one of those well-known types that responds well to this.
Any topic related to computers for making charts?
Charts are simply various data, of any kind displayed graphically. Spreadsheets and database programs usually have a charting facility built into them.
How data will store in DBMS?
Databases store data using any of the robust data structures for efficient management of data. They can use any of the record based logical models to represent the data. Hierarchical, Network or Relational data models.
What is a limitation of any map?
One limitation of any map is that it cannot show every detail and nuance of a geographical area. Maps have to simplify and generalize information, which can lead to a loss of specific information or context.
