We present a statistical analysis of power distribution of oscillations in aplage region in active region NOAA AR12651, observed jointly with ALMA (AtacamaLarge Millimeter/Submillimeter Array), IRIS (Interface Region ImagingSpectrograph), and SDO (Solar Dynamics Observatory). We employ coordinated ALMABand-6 (1.25 mm) brightness temperature maps, IRIS Slit-Jaw Images in 2796{\AA} passband, and observations in six passbands (1600 {\AA}, 304 {\AA}, 131{\AA}, 171 {\AA}, 193 {\AA} and 211 {\AA}) of AIA (Atmospheric ImagingAssembly) onboard SDO. We perform Lomb-Scargle transforms to study thedistribution of oscillation power over the observed region by means of dominantperiod maps and power maps. We study spatial association of oscillationsthrough the atmosphere mapped by the different passbands, with focus on thecorrelation of power distribution of ALMA oscillations with others. We do notobserve any significant association of ALMA oscillations with IRIS and AIAoscillations. While the global behavior of ALMA dominant oscillations showssimilarity with that of transition region and coronal passbands of AIA, theALMA dominant period maps and power maps do not show any correlation with thosefrom the other passbands. The spatial distribution of dominant periods andpower in different period intervals of ALMA oscillations is uncorrelated withany other passband. We speculate the non-association of ALMA oscillations withthose of IRIS and AIA be due to significant variations in the height offormation of the millimeter continuum observed by ALMA. Additionally, the factthat ALMA directly maps the brightness temperature, in contrast to theintensity observations by IRIS and AIA, can result in the very differentintrinsic nature of the ALMA oscillations compared to the IRIS and AIAoscillations.
