Today is my report for our PR II and the task that is given to me is to discuss about the types of descriptive Statistics. Your discussion sir is really Helpful to me, I can now explain it to my classmates about the process on How to get this frequency distribution step by step. Thank you sir❤️
@@doreencatulong1183 Some College Degree, ginagamit pa rin iyang Frequency Table. Lalo na sa mga BS Statistics ang course. Yes, tinuturo na siya JHS/SHS pa lang para malaman ng studyante kung paano mag solve, analyze, or makuha yung data.
I’m sorry sir but I think you forgot to include the approximate number of classes : this is the formula K = 1 + 3.322log N where: K= Number of classes and log N = Logarithm of the total number of observations. Example If the total number of performance of statistics class in the prelim exam is 40 , the number of classes would be K = 1 + 3.322log N K = 1 + 3.322log 40 K = 1 + 3.322(1.602059991328 or 1.6) K = 1 + 5.322043291192 or 5.3 K= 6.322043291192 or 6.3 Total number of classes: 6.3 After that you can get the class interval by using the formula : Range/no. Of classes Range divided by No. of classes 41/6.3 = 6.507936507937 or 7 that’s the total of class interval. All in all your right, 7 is the interval but you need to give the step-by-step procedure in order for the viewers to understand. Thank you po and Godbless .😇
sir may I ask kung hinahanap yung 3rd class interval, saan po dapat magsisimula magcount, sa bottom po ba or top? pls po sana ma tugunonan ito asap thank u
You can get your class interval by subtracting your highest value to the lowest value then divide it by the number of classes (k). K is obtained by using the Sturge’s Rule. K= 1 + 3.3 (log n), where n is the number of cases in the data set I hope this helps :)
hello sir, I would like to clarify a question of mine, I'm quite conflicted. I got a class interval of 6 and class width of 7, will it generate the same answer po ba when we compute for the mean, median, mode, standard d, if there's a difference in the construction of the table?
You need to find first the approximate number of classes before you can get the class interval: this is the formula K = 1 + 3.322log N where: K= Number of classes and log N = Logarithm of the total number of observations. Example If the total number of performance of statistics class in the prelim exam is 40 , the number of classes would be K = 1 + 3.322log N K = 1 + 3.322log 40 K = 1 + 3.322(1.602059991328 or 1.6) K = 1 + 5.322043291192 or 5.3 K= 6.322043291192 or 6.3 Total number of classes: 6.3 After that you can get the class interval by using the formula : Range/no. Of classes Range divided by No. of classes 41/6.3 = 6.507936507937 or 7 that’s the total of class interval. =7 is the class interval.
@@Danny-vg7ut good morning, I already explained the Log N step by step; the logarithm is the total number of observations, which is 40. There’s a formula that you need to follow “3.322log N” just try to analyze the problem. Thanks☺️
@@angelicajaneescranda395 i think he is referring to how did you come up with 1.6, i also wanted to know since the 3.332 is still there. Thank you in advance
@@angelicajaneescranda395 so we will divide the 40 from the result of 3.22logN? so what number can we put on N? can you show us an example? that you in advance
