![]() ![]() In this case we mix the parenthesis and the square bracket. In the third example (the one you are citing), the one boundary expression includes "equal to" and one does not ( x is greater than -4 and x is less than or equal to -1). When the boundary does NOT includes the number (greater than or less than, but not equal to), we use parentheses to notate the interval. When Sal shows the notation for the second interval (pink writing), the boundary expressions do NOT include "equal to" ( x is greater than -1 and x is less than 4). When the boundary includes the number (equal to), we use the square brackets to notate the interval. If you go back and watch Sal show the notation of the first interval (blue writing), both boundary expressions include "equal to" ( x is greater than or equal to -3 and x is less than or equal to 2). Keep in mind that this is a type of mathematical notation and not Grammar of any language that uses this type of punctuation. In Interval Notation, you actually can have a parenthesis on one side and a bracket on the other and have the notation be correct. Determine the median.This is actually a pretty good question and it's good to see that you are paying attention. ![]() ![]() The age groups of the employees are: 3 employees aged 52 years, 2 aged 32 years, 1. Out of the 500 adults, the majority of adults (70%) indicated that staying at home was their favorite evening 65 70 68 87 98 91 77 85 70 72 86 86 94 95 67 88 77 99 74 71įind 75th percentile for 30,42,42,46,46,46,50,50,54Ī Gallup poll investigated whether adults in Mumbai preferred staying at home or going out as their favorite way of spending time in the evening. Choose your own horizontal scales as long as you have more than 4 cells in each histogram. 2 4 5 5 7 7 8 8 8 12 What is the IQR?īelow is a collection of test scores from a class of 20 students. The data set represents the number of cars in a town given a speeding ticket each day for ten days. The size of pants sold during one business day in a department store is 32, 38, 34, 42, 36, 34, 40, 44, 32, and 34. To which number should the number 4 be changed between the numbers 4,5,7, 1,0,9,7,8, -3,5 to increase these numbers' arithmetic mean by 1.25? The table saw fit individual dice's wall frequency: Wall Number: 1 2 3 4 5 6 frequency: 8 7 5 11 6 13 Calculate the modus and median of the wall numbers that Radka fell. ![]() The last value will always equal the total for all observations since the calculator will have already added all frequencies to the previous total.Ī batsman scored the following number of runs in seven innings 35,30,45,65,39,20,40. The cumulative frequency is calculated by adding each frequency from a frequency distribution table to the sum of its predecessors. For example:į: 5 10 15 How to enter grouped data?Grouped data are formed by aggregating individual data into groups so that a frequency distribution of these groups serves as a convenient means of summarizing or analyzing the data.į: 5 10 15 How to enter data as a cumulative frequency table?Similar to a frequency table, but instead, f: write cf: in the second line. Each element must have a defined frequency that counts numbers before and after symbol f: must be equal. Write data elements (separated by spaces or commas, etc.), then write f: and further write the frequency of each data item. How to enter data as a frequency table?Simple. ![]()
