How are bar graphs and picture graph different?
Graphs are pictures that help us understand amounts. These amounts are called data. There are many kinds of graphs, each having special parts. A circle graph is shaped like a circle. It is divided into fractions that look like pieces of pie, so sometimes a circle graph is called a pie graph. Many times the fractional parts are different colors and a key explains the colors. A bar graph uses bars to show data. The bars can be vertical (up and down), or horizontal (across). The data can be in words or numbers. A picture graph uses pictures or symbols to show data. One picture often stands for more than one vote so a key is necessary to understand the symbols. A histogram is a special kind of bar graph. The data must be shown as numbers in order. A line graph shows points plotted on a graph. The points are then connected to form a line.
What are disadvantages of bar graph?
Hard to quantify partial iconsIcons must be of consistent sizeBest for only 2-6 categoriesVery simplisticNot as visually appealingBest for under 50 data valuesNeeds small range of dataNo exact numerical dataHard to compare 2 data setssome disadvantages u can find, can use only with discrete data n also the graph categories can be reordered to emphasize some effects over that
How do you make a appropriate data display of a bar graph?
To make an appropriate display, you must put the numbers on the side,the title above it,and the words underneath to describe what you are showing.For example,if it was weeks you would put ''weeks'' to show that you are describing the weeks.
Why on a line graph do all the points not fit exactly on the line?
because they are annoying like that.the reason it's called a line graph is because you join up the dots with a line.or you can leave the dots unjoined (a scatter graph) and draw a line of best fit.this is a line that doesn't touch any of the dots, but has a roughly equal amount on each side. there is no right or wrong line of best fit, but you cant have, say, 4 dots on one side and 1 on the other. the point of 'lines of best fit' are to show roughly where the dots go - the pattern of the data.HOWEVER, if drawing a line of best fit, you must first identify, then discredit any ANOMALIES, which are results of the data that are very different to the other answers; they do not fit into the pattern.
How do you make a data table?
To make a data table you must make a chart with how ever many columns you are going to need and then fill out your information.
How do you draw a trend line?
Well first you must have a sufisticated math problem worth plotting on a graph... Then you must carefully make a graph on a clean, sanitized piece of graph paper that is at least 8 in. by 11 in. Then you must expertly place the points of data where they are required... Then you acquire a moist ruler... Then you start your trend line where the set of carefully graphed data start/ends or meets the edges of your graph and draw a straight, clean line with a #2 pencil through your data...
What The best-fit line must go through all data points on a graph.?
No, the best fit line need not go through any data point on a graph.
The best fit line must go through all data points on a graph?
False
What is the scale for the line graph?
The scale can be anything that you choose - but you must give it with the graph.
Why should you draw a line of best fit when drawing a graph?
A best fit graph to some data is exactly that: it is a line which fits the data best according to some optimality criterion. There is a always a trade off in fitting a line to data: one can change the number of degrees of freedom of the underlying equation, which affects how close the line can get to the data points. With more degrees of freedom, the line can more closely approximate the data. This is not to say that more degrees of freedom are better: with too many degrees of freedom, one is merely fitting to the noise in the measurement of the data, and the line will predict subsequent data poorly, when both interpolating and extrapolating the existing data. This is an example of Occam's Razor: one must pick the simplest model which adequately fits the data.
How can you use range while planning to draw a line graph?
The data range must fit within the range of the axis.The data range must fit within the range of the axis.The data range must fit within the range of the axis.The data range must fit within the range of the axis.
What is the data percentage of circle graph?
All the data collated must add up to 100% in a circle graph or a pie chart
Where on a line graph records what you are measuring?
The information must be given on the axis label or in the title of the graph.
How can you decide whether a relationship is linear by studying the pattern in a graph?
The graph must be a straight line, and it must pass through the origin.
What must you do with data after you collect it?
I would suggest to put it in graph form.
If a straight line graph has a gradient of zero it must be horizontal?
120?
The graph of a relation must pass the vertical line test?
True
