stem and leaf plot
Frequency distribution a mathematical function showing the number of instances in which a variable takes each of its possible values.False
Stem-and-leaf plots are a method for showing the frequency with which certain classes of values occur. You could make a frequency distribution table or a histogram for the values, or you can use a stem-and-leaf plot and let the numbers show the same information.For instance, suppose you have the following list of values: 12, 13, 21, 27, 33, 34, 35, 37, 40, 40, 41. You could make a frequency distribution table showing how many tens, twenties, thirties, and forties you have:FrequencyClassFrequency10 - 19220 - 29230 - 39440 - 493You could make a histogram, which is a bar-graph showing the number of occurrences, with the classes being numbers in the tens, twenties, thirties, and forties. (The shading of the bars in a histogram isn't necessary, but it can be helpful by making the bars easier to see, especially if you can't use color to differentiate the bars.)The downside of frequency distribution tables and histograms is that, while the frequency of each class is easy to see, the original data points have been lost.You can tell, for instance, that there must have been three listed values that were in the forties, but there is no way to tell from the table or from the histogram what those values might have been.
It has two faces - a 'head' (displaying the monarch) and a 'tail' (showing 'Britannia' ) - It also has seven edges round the rim.
Tables and graph represent relations by showing the distribution of occurrence.
Florence Nightingale is usually credited with inventing the polar area diagram, there are earlier uses. Léon Lalanne used a polar diagram to show the frequency of wind directions around compass points in 1843. André-Michel Guerry is an earlier inventor of the "rose diagram" form, in an 1829 paper showing frequency of events foAlthough Florence Nightingale is usually credited with this graphical invention, there are earlier uses.

advantages: -very informative when examining how values are changing within the data set. -shows the running total of frequencies from the lowest interval up. disadvantages: -difficult to compare the frequencies between each data group. by Mr. Hsia
Manifest curriculum refers to the officially planned and documented curriculum that is implemented in the educational setting. It includes the instructional materials, assessments, and learning activities that are prescribed for students to achieve specific learning objectives. This is contrasted with the hidden curriculum, which consists of the unintended lessons that students may learn from the school environment.
