Question

Ledolter and Hogg (see References) report that a manufacturer of metal alloys is concerned firm's alloy filaments. Fifty filaments are selected and their melting points determined. The following results were obtained: 320 326 325 318 322 320 329 317 316 331 320 320 317 329 316 308 321 319 322 33.5 318 313 327 314 329 323 327 323 324 314 308 305 328 330 322 310 324 314 312 318 313 320 324 311 317 325 328 319 310 324

please find the median and mode.

Answer 1

Solution:

Given data=

320,326,325,318,322,320,329,317,316,331,320,320,317,329,316,308,321,319,322,335,318,313,327,314,329,323,327,323,324,314,308,305,328,330,322,310,324,314,312,318,313,320,324,311,317,325,328,319,310,324

First dara arrange highest to lowest

335, 331, 330, 329, 329, 329, 328, 328, 327, 327, 326, 325, 325, 324, 324, 324, 324, 323, 323, 322, 322, 322, 321, 320, 320, 320, 320, 320, 319, 319, 318, 318, 318, 317, 317, 317, 316, 316, 314, 314, 314, 313, 313, 312, 311, 310, 310, 308, 308, 305

median = median is the middle most observation of data set

=320+320/2

=640/2

median=320

Mode = It represent the repeated value in data set

Mode=329,328,327,325,324,323,322,320,319,318,317,316,314,313,310,308
