Bethan-Bearings Bearings are a measure of direction, with North taken as a reference. If you are travelling North, your bearing is 000°, and this is usually represented as straight up on the page. If you are travelling in any other direction, your bearing is measure clockwise from North. Example Look at the diagram below: If you walk from O in the direction shown by the red arrow, you are walking on a bearing of 110 °. REMEMBER: Bearings are always measured clockwise from North and are given as 3 digits. Here are some more examples: Note that the first two bearings above are in directly opposite directions to each other. Example Questions Example Question 1 Points of the compass can all be converted into bearings. Find the bearings for: (a) East (E) (b) South (S) (c) South-East (SE) Example Question 2 A ship sails from A to B on a bearing of 120°. REMEMBER: Bearings in exactly opposite directions are called back bearings and are always 180° apart. Practice Questions to see whether you are correct. (b) 200°
Ratios: Jacob Thomas A ratio compares values. A ratio says how much of one thing there is compared to another thing. There are 3 blue squares to 1 yellow square Ratios can be shown in different ways: A ratio can be scaled up: Here the ratio is also 3 blue squares to 1 yellow square, even though there are more squares. Using Ratios The trick with ratios is to always multiply or divide the numbers by the same value. Example: Recipes Example: A Recipe for pancakes uses 3 cups of flour and 2 cups of milk. So the ratio of flour to milk is 3 : 2 To make pancakes for a LOT of people we might need 4 times the quantity, so we multiply the numbers by 4: In other words, 12 cups of flour and 8 cups of milk. The ratio is still the same, so the pancakes should be just as yummy. "Part-to-Part" and "Part-to-Whole" Ratios The examples so far have been "part-to-part" (comparing one part to another part). But a ratio can also show a part compared to the whole lot. Example: There are 5 pups, 2 are boys, and 3 are girls Try It Yourself Scaling
Histograms | gcse-maths-revision, statistics-handling-data, histograms Histograms are similar to bar charts apart from the consideration of areas. In a bar chart, all of the bars are the same width and the only thing that matters is the height of the bar. In a histogram, the area is the important thing. Example Draw a histogram for the following information. (Ignore relative frequency for now). When drawing a histogram, the y-axis is labelled 'relative frequency' or 'frequency density'. If you are having problems working out the height of each of the bars, you can use the formula Area of bar = frequency x standard width This video shows you how to draw a Histogram
Averages - Callum Mean There are three main types of average: mean - The mean is what most people mean when they say 'average'. It is found by adding up all of the numbers you have to find the mean of, and dividing by the number of numbers. So the mean of 3, 5, 7, 3 and 5 is 23/5 = 4.6 . mode - The mode is the number in a set of numbers which occurs the most. This video shows you how to calculate the mean, median and mode This video shows a very catchy song to help you remember the difference between these 3 terms Grouped Data When you are given data which has been grouped, you can't work out the mean exactly because you don't know what the values are exactly (you just know that they are between certain values). Example Work out an estimate for the mean height, when the heights of 23 people are given by the first two columns of this table: In this example, the data is grouped. A good way of setting out your answer would be to add two columns to the table, as I have. Moving Averages Mode Range The Median Value
