Oct 13, 2025 by wbrum.org 47 views

Introduction

Blood platelet count is a crucial indicator of an individual's health, particularly in males. A normal platelet count ranges from 150,000 to 450,000 platelets per microliter (µL) of blood. However, an abnormal platelet count can be a sign of various health issues, including bleeding disorders, blood cancers, and other conditions. In this article, we will explore the frequency distribution of blood platelet count in males and identify the lower class limits, upper class limits, class width, class midpoints, and class boundaries.

Frequency Distribution of Blood Platelet Count in Males

The following table represents the frequency distribution of blood platelet count in males:

Platelet Count (1000 cells/µL)	Frequency
150-175	10
176-200	20
201-225	30
226-250	25
251-275	15
276-300	10
301-325	5
326-350	2
351-375	1
376-400	1
401-425	1
426-450	1

Calculating Class Limits, Class Width, Class Midpoints, and Class Boundaries

To calculate the class limits, class width, class midpoints, and class boundaries, we need to follow these steps:

Lower Class Limits

The lower class limits are the lowest values in each class interval. To calculate the lower class limits, we need to subtract half of the class width from the lower limit of each class interval.

Platelet Count (1000 cells/µL)	Lower Class Limit
150-175	150 - (175 - 150) / 2 = 150 - 12.5 = 137.5
176-200	176 - (200 - 176) / 2 = 176 - 12 = 164
201-225	201 - (225 - 201) / 2 = 201 - 12 = 189
226-250	226 - (250 - 226) / 2 = 226 - 12 = 214
251-275	251 - (275 - 251) / 2 = 251 - 12 = 239
276-300	276 - (300 - 276) / 2 = 276 - 12 = 264
301-325	301 - (325 - 301) / 2 = 301 - 12 = 289
326-350	326 - (350 - 326) / 2 = 326 - 12 = 314
351-375	351 - (375 - 351) / 2 = 351 - 12 = 339
376-400	376 - (400 - 376) / 2 = 376 - 12 = 364
401-425	401 - (425 - 401) / 2 = 401 - 12 = 389
426-450	426 - (450 - 426) / 2 = 426 - 12 = 414

Upper Class Limits

The upper class limits are the highest values in each class interval. To calculate the upper class limits, we need to add half of the class width to the upper limit of each class interval.

Platelet Count (1000 cells/µL)	Upper Class Limit
150-175	175 + (175 - 150) / 2 = 175 + 12.5 = 187.5
176-200	200 + (200 - 176) / 2 = 200 + 12 = 212
201-225	225 + (225 - 201) / 2 = 225 + 12 = 237
226-250	250 + (250 - 226) / 2 = 250 + 12 = 262
251-275	275 + (275 - 251) / 2 = 275 + 12 = 287
276-300	300 + (300 - 276) / 2 = 300 + 12 = 312
301-325	325 + (325 - 301) / 2 = 325 + 12 = 337
326-350	350 + (350 - 326) / 2 = 350 + 12 = 362
351-375	375 + (375 - 351) / 2 = 375 + 12 = 387
376-400	400 + (400 - 376) / 2 = 400 + 12 = 412
401-425	425 + (425 - 401) / 2 = 425 + 12 = 437
426-450	450 + (450 - 426) / 2 = 450 + 12 = 462

Class Width

The class width is the difference between the upper and lower class limits.

Platelet Count (1000 cells/µL)	Class Width
150-175	187.5 - 137.5 = 50
176-200	212 - 164 = 48
201-225	237 - 189 = 48
226-250	262 - 214 = 48
251-275	287 - 239 = 48
276-300	312 - 264 = 48
301-325	337 - 289 = 48
326-350	362 - 314 = 48
351-375	387 - 339 = 48
376-400	412 - 364 = 48
401-425	437 - 389 = 48
426-450	462 - 414 = 48

Class Midpoints

The class midpoints are the average of the lower and upper class limits.

Platelet Count (1000 cells/µL)	Class Midpoint
150-175	(137.5 + 187.5) / 2 = 162.5
176-200	(164 + 212) / 2 = 188
201-225	(189 + 237) / 2 = 213
226-250	(214 + 262) / 2 = 238
251-275	(239 + 287) / 2 = 263
276-300	(264 + 312) / 2 = 288
301-325	(289 + 337) / 2 = 313
326-350	(314 + 362) / 2 = 338
351-375	(339 + 387) / 2 = 363
376-400	(364 + 412) / 2 = 388
401-425	(389 + 437) / 2 = 413
426-450	(414 + 462) / 2 = 438

Class Boundaries

The class boundaries are the values that separate each class interval.

Platelet Count (1000 cells/µL)	Class Boundary
