In this case 5 \u2013 1 = 4. ( ) \u00f7 4 = 49. Step 4 Remember that we squared the numbers in step 2 so. now we must find the square root of 49. This number is called the standard deviation and is the measure. of how far each value is from the mean. standard deviation. The formula for standard. deviation is: in this case = 7. When the standard deviation is low it means the scores are close to the mean. When it is high it means they are spread out from the mean. In this case it is a high number in relation to the mean, so the numbers are spread out from the mean.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
