In addition to the above results, this study also resulted a program shape to facilitate the calculation of item analysis. The distinguishing power of items showed that 1 item (2.50%) was very good, 9 items (22.50%) were good, 10 items (25%) were moderate, 14 items (35%) were less good and 6 items (15%) were bad. The difficulty level of items was not good because the items balances including easy, medium and difficult were not proportional, the proportional balance was 3-5-2 or 3-4-3. The reliability of items was quite good where the reliability coefficient value more than r tabel was 0.558 based on three formulas which were Anova Hoyt, Cronbach alpha and IBM SPSS Statistics 22. The results showed that 22 questions (55%) were valid and 18 questions (45%) were invalid. The datas were analyzed by using several formulas of validity, reliability, level of difficulty, distinguishing powerand the use of IBM SPSS Statistics22 software and anates V4 software. The datas consisted of 128 students’ answer sheetsin social class XII academic year 2014/2015. The researchused quantitative descriptive method and documentation technique. It also allows to use HERA data on hadronic final states in the tuning of hadronisation models.This study aims to( 1) determinethe items quality of odd semesterfinal examin social class XII mathematics subject academic year 2014/2015 in terms of validity, reliability, level of difficulty, and distinguishing power, (2) createa program shape for calculating validity, reliability, level of difficulty and distinguishing power. The extension to deeply inelastic processes provides the opportunity to validate the merging of matrix elements and parton showers in multi-scale kinematics inaccessible in other collider environments. The various sources of theoretical uncertainties of the approach are discussed and quantified. Different hadronic final states, defined by jets or individual hadrons, in deep-inelastic scattering are analysed and the corresponding results are compared to HERA data. Using an extension of the recently introduced method for merging truncated parton showers with higher-order tree-level matrix elements, it is possible to obtain predictions which are reliable in all kinematical limits. Hadronic final states in this kinematical setting are characterised by the presence of multiple kinematical scales, which were up to now accounted for only by specific resummations in individual kinematical regions. We extend the multi-purpose Monte Carlo event generator Sherpa to include processes in deeply inelastic lepton–nucleon scattering.
