If the modal age of the patients is 54, then find the value of x.

One healthcare center working for the welfare of the patients suffering from 'Dengue', recorded the following information: Age of Patients Number of Patients 0-15 8 15-30 5 30-45 x 45-60 16 60-75 12 75-90 9 If the modal age of the patients is 54, then find the value of x. cbse 10th maths old board exam question paper 2024 2025 mathematics standard question in statistics given the mode to find missing frequency icse bsc subsidiary statistics measures of central tendency In this video we solve a classic grouped data statistics problem about a dengue patient-age frequency table. You’ll see how to find the missing frequency 𝑥 x given that the modal age is 54 years. This topic belongs to statistics / data handling / central tendency and is widely tested in IGCSE / Cambridge International, A-level / Edexcel, IB Mathematics (SL/HL), AP Statistics, SAT Math (if extended topics), CBSE / ICSE, and in many university entrance exams or quantitative aptitude tests (like GRE, GMAT, MAT). We are told the modal age is 54. That means the modal class interval is 45-60, and we use the grouped-daThis problem type appears under “mode of grouped frequency distribution” in IGCSE / Cambridge 0580 / CIE syllabus (question papers on mean/modal class)ta mode formula:Also in CBSE / ICSE / CBSE statistics chapters on central tendency, and in many state board exams. Many competitive / aptitude / data interpretation sets include grouped data mode and missing frequency puzzles. The formula and approach also show in reference pages on mode of grouped data. By the end of this video, you'll know (1) how to identify the modal class, (2) how to set up the formula, (3) how to solve for a missing frequency, and (4) how to check reasonability (frequency must be positive, integer). This is useful for students preparing for IGCSE Math, Cambridge A statistics, IB, AP Statistics, GRE quantitative, MBA entrance, school board exams in India, UK, UAE, Nigeria, Kenya, etc. If you're following CBSE Class 10 / CBSE Class 11 / CBSE Class 12, the statistics / data handling chapters often ask mean/median/mode, cumulative frequency, etc. Similarly in UK GCSE / IGCSE, in A-level modules, in IB, AP, SAT/ACT extended. This video helps clarify one tricky variant: missing class frequency given the modal value. Watch carefully through the stepwise algebra, and if you pause and try along, you’ll reinforce your command. Share the video with classmates preparing for board exams or international curricula. Drop comments if you want more worked examples (median, mean, cumulative frequency). Don’t forget to like & subscribe if this helps. Global learners from India, USA, UK, Nigeria, UAE, Canada, Australia, Singapore, Malaysia — this concept is common to many curricula. Mastering grouped data mode and missing frequency problems boosts your confidence in quantitative sections and statistics chapters across systems. #cbse #mathematics #maths #math #cbsemaths #ncertmaths #icse #statistics #groupeddata #modedistribution #central tendency #dataanalysis #IGCSE #APStatistics #IBMath #CBSE #examprep #quantitativeaptitude #mathexam #datainterpretation #entranceexams #statisticsproblems
