FIR and IIR are digital filters that are commonly used in digital signal processing. There are only a few components that make up these filters, but these components can be arranged in various ways to make complicated filters for use in digital signal processing.
In some statistical analyses, the median is a better predictor of the expected value for a set of observations than the mean (average). To calculate the median, in the simplest terms, if you have an odd number (n) of items in an ordered set, the median is the value where (n+1)/2 is the row containing the median value. If there is an even number of rows, the value is the average (mean) of the two values appearing in the n/2 and the 1+n/2 rows.
Draw a dotplot of the data; then determine the mode, the median, the mean and the range using the dotplot. Write an explanation of how you used the dotplot to determine each value. a) Mode b) Median c) Mean d) Range 2.how students how to work to the middle to find the median. Investigate what happens if there are two pieces of data in the middle. Be especially careful calculating the mean. Some students will divide by the number of points on the horizontal axis, not by the number of pieces of data.
