This nine point scale provides an easy way to compare individuals without worrying about small differences in raw score. Stanine scores are typically used with standardized testing and are often reported on the results along with raw scores. Example Data We will see an example of how to calculate stanine scores for a sample data set. There are 100 scores in the table below that are from a population that is normally distributed with a mean of 400 and a standard deviation of 25. The scores have been ranked in ascending order as 351 380 392 407 421 351 381 394 408 421 353 384 395 408 422 354 385 397 409 423 356 385 398 410 425 356 385 398 410 425 360 385 399 410 426 362 386 401 410 426 364 386 401 411 427 365 387 401 412 430 365 387 401 412 431 366 387 403 412 433 368 387 403 413 436 370 388 403 413 440 370 388 403 413 441 371 390 404 414 445 372 390 404 415 449 372 390 405 417 452 376 390 406 418 452 377 391 406 420 455 Calculation of Stanine Scores We will see how to determine which raw scores become which stanine scores. The first 4% of ranked scores (raw scores 351-354) will be given a stanine score of 1.The next 7% of ranked scores (raw scores 356-365) will be given a stanine score of 2.The next 12% of ranked scores (raw scores 366-384) will be given a stanine score of 3.The next 17% of ranked scores (raw scores 385-391) will be given a stanine score of 4.The middle 20% of ranked scores (raw scores 392-406) will be given a stanine score of 5.The next 17% of ranked scores (raw scores 407-415) will be given a stanine score of 6.The next 12% of ranked scores (raw scores 417-427) will be given a stanine score of 7.The next 7% of ranked scores (raw scores 430-445) will be given a stanine score of 8.The next 4% of ranked scores (raw scores 449-455) will be given a stanine score of 9. Now that the scores have been converted to a nine point scale, we can easily interpret them. A score of 5 is the midpoint and is the average score. Each point in the scale is 0.5 standard deviations away from the mean.
